Cheapest VPS Management Technologies

Here are some technologies that are often used for virtualization of the cheapest VPS servers and consider them in more detail. OpenVZ is implemented at the operating system level. In this case, all virtual machines are based on a single modified Linux kernel. Each of them is a separate server. The features of the technology include: • Use of Linux, which limits the choice of distributions; • Use only file system - ext4; • No modification of the kernel, which limits the launch of non-standard modules (OpenVPN, PPTP, IPSEC and others); • The OS Administrator has access to all files hosted on a dedicated server. By KVM technology, virtualization is implemented through the hypervisor virtual machine manager. Cheapest VPS servers on KVM technology has advanced features: • Work with any operating system, including Windows, FreeBSD, etc .; • Formatting disk space for any file system; • Server management in the early stages of boot (including the BIOS screen), using the RFB protocol; • Ability to modify the OS kernel; • Only the owner has access to the contents of the virtual server. The OpenVZ technology assumes the dynamic distribution of available resources among all machines. The main advantage is the ability to change the limits of allocated capacity without rebooting. At the same time, this approach leads to dependency on neighboring servers. Excessive load on a single virtual server can lead to a decrease in the performance of the entire cluster. KVM technology eliminates performance degradation. Each virtual server receives a strictly defined amount of computing resources and cannot go beyond them. At the same time, KVM is distinguished by the highest reliability comparable to the fault tolerance of physical machines. Minus technology is less flexible: if the amount of RAM can be changed after a reboot, the resizing of the disk space can no longer be changed. These virtualization technology differences play a role only if the virtual server is planned to be used to host specific applications with special requirements for kernel modification, for example.

Choosing a VPS servers for your project and where to find it

How to make the project run successfully? But is it one thing to launch a project? After all, it is necessary to ensure its maximum performance at any time of the day or night, regardless of the load. Only then the project will be profitable and will delight its visitors with useful information or others. Often, many site owners are worried about the initial launch. The most inexperienced of them think that launching your own project is the most difficult thing, but then everything will be much easier. However, this is not always the case. In addition to successfully selecting a niche, successfully selecting a site design, writing quality texts, there is another sensitive question. And it concerns the other. It is necessary to choose the cheapest VPS server host in the most competent way. This is a great type of hosting, which has long gained a high level of popularity. After all, if you order a reliable VPS servers, you can provide your website, your favorite project with high stability of work, as well as full protection, and of course high speed of work. Regular hosting and VPS are not competitive services. Both types of hosting are suitable for different tasks and types of web resources. It all comes down to what your needs and budget are. In many cases, the usual hosting is suitable for many site owners. It is simpler from a technical point of view and is usually controlled through a convenient panel. On the other hand, for serious, loaded and non-standard projects, VPS hosting is required. This will provide scalability and allow you to customize the server for your own needs. Administration needs to be carried out independently. For all additional services you need to pay extra provider. VPS or hosting for personal use has a rich functionality and, in fact, is ahead of virtual hosting. But, not in the event that you are the owner of a site with high traffic, run several projects or a large corporate portal. Benefits of shared hosting: • Diverse selection of tariffs; • Traffic is not limited; • There are no problems with administration; • Test periods and bonus programs are provided.

What is VPS and usage tips?

Each VPS shares the resources of a physical server, but they are separated from each other. If there are any problems on one VPS server or it consumes too much resources, it will not affect other VPS located on the same physical media. VPS service is intermediate between a virtual hosting and a full-featured dedicated server. There are many positive aspects of choosing a VPS-server: it is much cheaper than a fully dedicated server, but it has almost the same features; gives more freedom and flexibility in comparison with limits and limitations of virtual hosting. If you compare VPS with virtual hosting, then on the latter you have extremely limited administrative rights and cannot determine the software configuration. VPS features include performing any actions from your control panel and you do not need to contact technical support every time you need to update or configure something. With VPS, you are limited only by the capabilities of the selected server, so choose powerful enough for the needs of your website. If you think that you do not have the necessary technical knowledge, then many hosting providers offer the full administration of your VPS at an additional cost. In most cases, the functional part of a virtual dedicated server is almost as good as real servers. Full root access allows you to install any add-ons and fine-tune the server configuration to suit your needs. What VPS is for: for large web projects that require setting up the operating system and independently determining various software configurations. Benefits: • unlimited administrator rights and root access; • the ability to determine the software configuration; • independence from other users located on the same physical machine; • dedicated virtual server resources. Disadvantages: • the price is higher than the virtual hosting; • VPS power is still lower than that of a dedicated server; • difficulties in administering without the necessary knowledge.

How to avoid mistakes when choosing a hosting

Everyone says that they learn from mistakes, but sometimes these mistakes can lead to very large losses. Therefore, your attention would like to introduce a few common mistakes that are allowed when choosing a hosting. Choosing the cheapest tariff plan Of course, you can not blame a person for the desire to save money. But still you have to be realistic about what you can and need to save. The amount of money that you could save by choosing one or another provider is minimal, so in the long run your costs will pay off if hosting is expensive. So it's better to stay away from anything that looks too cheap and too good to be true. On the other hand, you do not necessarily have to pay a lot for quality hosting. The choice of a knowingly expensive hosting does not always justify itself. Ignoring the terms of use Let's be honest, many of us tend to ignore the conditions, ordering some kind of service or product online. Probably, many people are familiar with the situation when a checkmark next to "I read and agree with the terms of use" is put simply on subconscious level. But sometimes this practice can be fatal. Always carefully read the terms of any contracts, thereby you can protect yourself from the occurrence of unpleasant situations. Big plans It is important to correctly evaluate how much traffic and resources such as memory and disk space you will need. If you do not have a truly unique and exactly fascinating idea for a new product or service, you are likely to have a slow start before you build an audience and attract enough money to justify the choice of a large hosting plan. It is quite easy to upgrade and promote your site after it is created, so starting work with a cheaper hosting plan is quite a safe thing, in the future you can just change it. Do not worry too much about what you will need in the future, and instead focus on how you can make your new site profitable in its present form. No technical support Now if you adhere to such a rule, then most likely, an online broadcast for your site can be difficult. Technical support should be, and it is important to have a connection with it not only by email or chat, but also by phone, and preferably 24x7.

What is the reason for the global increase in the number of hyper scalable data centers?

In April 2017, there were 320 hyper-scalable data centers in the world, and in December their number was 390. Synergy expects the number of hyperscale data centers to increase to 400 in the first quarter of 2018 and reach 500 in 2019. Location and pricing According to a Synergy study, most of hyper-scalable data centers are located in the United States (44%), China accounts for 8%, and Japan and the United Kingdom at 6% each. In Australia and Germany, there are 5% of data centers, and in Singapore, Canada, Brazil and India, they have deployed 3% of the total number of such data centers. According to Deloitte and Gartner, in 2016, global spending on traditional infrastructure amounted to 1045 billion dollars. However, this figure is decreasing: according to forecasts, in 2018 it will fall to $ 1005 billion. At the same time, the demand for cloud service providers will increase, and spending on cloud solutions from 2016 to 2018 will increase from 361 to 547 billion dollars. For example, in March last year, Google announced that their spending on expanding its data center network over the past three years amounted to $ 30 billion. And Microsoft and Amazon invest $ 10 billion in data center infrastructure annually. Opposite trend: micro DC Hyperscale data centers are mainly used for the development and training of artificial intelligence, work with IoT and in other areas where you need to process a large amount of data. However, not all companies will benefit from the development of hyper-scalable data centers, since working with them requires large investments in infrastructure development. Therefore, in recent years, such a solution as a micro-data center has gained popularity. Micro data centers, or modular data centers, are a set of blocks necessary for assembling a DIY data center. Designing and deploying a micro-data center depends on the client’s wishes: he can choose the required number of racks himself and create a fully-ready data center in a month (we have already written about modular data centers here). Such a data center is beneficial for three reasons: the equipment does not take up much space, the data center does not require special staff to deploy capacity and consumes less electricity than a traditional data center. The technology is already in use in IoT, retail, video streaming or banking. According to Research and Markets, the microCOD market will grow from $ 2 billion in 2017 to $ 8 billion by 2022. At the same time, the average annual growth rate will be 26%.

In what way does cloud hardware matter?
Hosting
In what way does cloud hardware matter?

We are assured that the hardware in the cloud no longer plays a special role, but is it really so? Standard iron copes well with the task On the basis of large reserves of mass-class hardware, modern cloud service providers create an environment for computing as a commercial service. This approach is called overscaling. It allows them to use virtualized storage media, a network and computing resources that are deployed on demand according to special rules applied at the time of their allocation. But how does this affect reliability? Providers do not expect that the hardware will never or very rarely fail, instead they foresee equipment breakdowns and cope with them in such a way that they in any way or at a minimum affect the services provided to customers. In other words, with this approach, the provider does not spend all the money to achieve the desired remaining percentage of fault tolerance. Instead, he buys inexpensive equipment and forms systems with high density of iron from it, as a result of which he can save on infrastructure scale due to the reduced area and reduced requirements for cooling and electricity. These savings are then reflected in the prices offered to the buyer. It turns out that a large cloud provider is able to provide the same, if not higher, reliability, like those who deploy more expensive infrastructure. At the same time, he has more opportunities to configure his systems, he can add the functionality required in a multi-tenant hyper-scaled cloud environment, and remove all unnecessary. Does hardware class matter? The question remains: when buying cloud services, does it make any difference what equipment is used there? Taking into account the fact that the cloud provider offers services, solutions and applications, the formal answer is no. But looking at cloud providers offering the richest set of corporate services, it becomes obvious that the basis of this menu of services is hyper-scaled hardware. In itself, the equipment of corporate customers does not care, but it is precisely it that is responsible for the reliable operation of applications at a price that these customers are willing to pay. And this already gives the question of the choice of iron great importance.

Getting offshore dedicated server for rent

Getting offshore dedicated server for rent

The concept of renting a offshore dedicated server is to provide it to the user for a certain time agreement. The data center provide server rental service and the customer sign a contract, where the price and the term of the service, and other provisions for the operation of the server are indicated. It should be noted that getting a server for rent provides much more opportunities than using hosting. You can not only use powerful servers to store important information about the company, but also perform various actions. Renting a server means providing the owner of the Internet resource or its principal with the use of a physical and virtual server. It is worth noting that the virtual machine is several times less than its physical counterpart. The reason for this is very simple. VPS is hosted on a dedicated server and can be controlled remotely. On this server can be multiple VPS. From this it follows that the client leases a computing device with a special computer program installed on it, which is located at the landlord. What is the purpose of using a server? Given the moment that the server has a flexible system of settings, the tenant can adapt it to solve specific problems. If necessary, you can install the necessary software and order dedicated server hosting Windows. Often they serve as a platform for placing business services, corporate sites in the network. Such a server is needed for sales through the Internet, game projects or the ability to participate in team games. VPS will help you to perform diverse tasks, create complex programs and libraries, virtual desktop, as well as store and archive arrays of information. The privilege of offshore servers is the ability to host any content, as well as freedom of expression. Adult, malicious scripts / pages, as well as SPAM is an exception, and hosting such content on our servers is strictly prohibited. Complaints and DMCA notifications will be redirected to customers to take the necessary measures, but in most cases no action is required.

What are the special issues and what is the dedicated server definition?

This is a separate physical machine, all the resources of which are provided to the client. The client receives full administrative access to the management of software and hardware components of the server without access restrictions. Substantial computing power and high bandwidth of the communication channel allow placing projects of any complexity on a dedicated server: from online stores and high-traffic forums to mail servers and database servers. The advantages of a dedicated server are: • Ability to install any system software, which, in turn, makes it possible to install any CMS. • Own IP address, which is not shared with other ISP clients. • Ability to create snapshots, which allows you to instantly create a backup / restore after a failure - this reduces the duration of site downtime. • Complete freedom to customize the system for your project. • Ability to host an unlimited number of sites, create an unlimited number of mailboxes, FTP, SSH-accounts. • The ability to change the server configuration at any time, the ability to return unused resources back - will have to pay less. How to choose a provider? When choosing a the UK dedicated servers provider, you need to pay attention to the following factors: • Having your own data center: if the company has invested in its own DC, then at least the company is serious. Consider the level of DC. At Xelent.ru, the equipment is located in its own TIER-III level DC - in fact, 100% availability is ensured. • There is a test period and round-the-clock support: it’s good if you have the opportunity to try it for a while before buying a VDS. Also, the presence of round-the-clock support says a lot - if only the support was actually like that. Check out technical support work at night. • Availability of insurance against data loss: the presence of such insurance is not only monetary compensation in case of data loss, but also an additional guarantee that the provider will do everything to keep the data of customers. • Pricing: there are providers that provide their services very expensive, and the quality of these services leaves much to be desired. Others provide high-quality VDS at reasonable prices. Another point that I want to highlight separately - the presence of the necessary software licenses. Especially this moment is relevant for Windows servers: is the Windows license included in the rental price of the VDS or will it have to be paid extra? That's all. We hope this small note will help you to understand dedicated server definition.

Dual-Mode Enterprise SSD Controller from Silicon Motion

Taiwanese company Silicon Motion announced the development and launch of a new NAND memory controller for the release of enterprise-class SS22 SM2270. The development of the new product has become a confirmation of the company's policy of avoiding dependence on the consumer SSD market. The market for servers and supercomputers is bigger than the market for home devices. Therefore, every developer seeks to dive into the corporate environment whenever possible. Silicon Motion SM2270 controller has one yet unique feature. It can operate in one of two modes: as a normal controller with a PCI Express bus with support for the NVMe protocol or in the Open Channel mode. To do this, the controller is equipped with a regular or customized firmware upon the request of customers. In the Open Channel mode, which only penetrates the drive market, control over the SSD memory array is given to the operating system. For example, a preliminary version of the Open Channel specifications is supported by the Microsoft Denali environment. According to the developers, in some scenarios the operating system will cope better with data management on the SSD than the controller integrated into the drive. In any case, it will be possible to manage data in storages more diversely. Silicon Motion SM2270 controller relies on the powerful "tripled" dual-core ARM Cortex-R5 architecture. The interface supports up to 8 PCI Express 3.0 lanes with support for the NVMe 1.3 protocol. 16 channels lead to the NAND memory array, which gives the maximum SSD capacity up to 16 TB. All NAND memory types are supported, including the latest 96-layer 3D NAND with TLC and QLC cells. The maximum throughput of the controller in reading random 4-Kbyte blocks reaches 800,000 IOPS. In addition, the controller SM2270 supports a number of proprietary technologies Silicon Motion. This is the power loss protection of Power Loss Protection, the 6th generation of NANDXtend technology, which includes error correction with machine learning algorithms, as well as end-to-end data loss protection using SRAM or DRAM buffers. Finally, the new controller can operate in an extended temperature range, ensuring data integrity in a challenging working environment.

What is HPE focused on and what innovations to expect

The main focus of the company is on such technologies as artificial intelligence, peripheral computing, autonomous data centers and intelligent storage. Autonomous data center. It is about creating a data center that works in automatic mode and does not require maintenance personnel. It is clear that there can not do without the built-in AI. The company promotes two main products: the Nimble storage system and InfoSight is a cloud-based tool for monitoring and managing the maintenance of this system, which almost completely automates support. InfoSight collects information from sensors, teaches itself, looks for patterns, and then makes recommendations based on the experience gained, and also automatically performs routine actions, such as updating firmware. In the future, HPE is going to extend the effect of InfoSight to all its products and thereby implement AI for an autonomous data center. Artificial Intelligence. In the field of AI, data, means of processing and storing them, as well as the speed of data processing play a huge role. One of the steps in this direction is the acceleration of applications through the use of new high-speed non-volatile SCM storage devices connected via the NVMe protocol to 3PAR and Nimbe storage controllers. HPE in partnership with Intel, is implementing SCM technology in its 3PAR and Nimble storage platforms. According to Vladislav Logvinenko, now the best option is to use NVMe and SCM for caching. Peripheral Computing. The need to perform computational processing outside the data center appeared in connection with the spread of the Internet of Things (IoT). There are two separate worlds: operational technologies and information technologies. The first includes various sensors, sensors and other devices that generate a huge amount of data. But you need to analyze this information quickly. Therefore, it is advisable to do this not in data centers, but as close as possible to the place of data generation. HPE offers for this a family of Edgeline Converged System devices that allow you to remove computing resources from data centers and place them near IoT data sources.

New AMD processor will not require software optimization

In early January, AMD made announcement of the future 7-nm Ryzen 3000 processors, based on a fundamentally new Matisse design, but many details about their structure and features remained behind the scenes. AMD's Chief Technology Officer expressed an extremely pleasant statement for AMD fans: existing software will not have problems with promising processors, and no additional rework or optimization will be required. This is important, because at one time, the first generation Ryzen processors were seriously affected by non-optimized software, demonstrating in it the performance is noticeably lower than expected. The problem was particularly pronounced in tasks sensitive to delays, for example, in many games. AMD even had to make special efforts to get developers to release patches of software code with special optimizations for the unique Zen architecture, which in some cases really allowed to increase the performance of Ryzen. Now the company assures that the re-optimization of operating systems and software for future Ryzen is not needed. The optimizations that were required when we released the first Ryzen were related to the concept of Core Complex. But AMD successfully worked with Windows and Linux, in which the correct recognition of the Core Complex appeared, and now the workloads work correctly with processors with such an organization. Now, each combined core combines four computing cores and 8 MB of L3 cache, and the Zeppelin chip, on which modern Ryzen processors are based, contains two such complexes and a set of external controllers. In future Ryzen on the Zen 2 architecture, this scheme will obviously change somehow, since the memory controllers and peripheral interfaces will be moved to a separate I / O chiplet. However, chiplets with cores are likely to retain their block construction from Core Complex, which makes it easy to scale the number of cores.

What IPv4 broker do and how to transfer subnet?

The rules of any RIR are developed by the Internet community in order to provide those companies that need IPv4 addresses with the opportunity to continue working with the IPv4 protocol, despite the limited number of available addresses of the specified protocol. And according to them, organizations that have free pools of IPv4 addresses can transfer them to other organizations. Over the past few years, some organizations have accumulated a large number of IPv4 addresses and now such organizations may have more than necessary IPv4 addresses. Returning unnecessary addresses is carried out free of charge, since the companies themselves received such addresses for free too. In addition, organizations can give unnecessary addresses to other companies that have documented the need for IPv4 addresses. The transfer of address pools must be in accordance with the rules that are reflected in the policies of each of the RIRs. Such actions will help to make the best use of the remaining addresses. So far, it is possible to rent or buy IPv4, reissuing to another company. The basis for the sale transaction is an IP transfer agreement between LIRs. It is to meet these needs that IPv4 brokers work. The most in-demand IPv4 broker service is trench pool assistance. Stages of IPv4 pool transfer: • Consideration of your request for IPV4 addresses (size, class, minimum and maximum price) • Search for a seller subnet, intermediary financial negotiations • Establishment and control over the transfer of RIR documents, preparation for transfer (removal of route facilities, verification of administrative correspondence) • Creating a secure system of financial flow, through a trusted third party or a direct contract • Financial transaction follow-up, initialization and management with RIPE, subnet transfer • Closing a transaction when the RIR database is updated with your data

What problems can you face if you need to buy ipv4 space?

In the face of the exhaustion of IPv4, the only way to continue the development of the Internet will be to use IPv6 addresses. However, this is now fraught with organizational and financial difficulties, which can be considered in a separate article. Here we talk about IPv4. In the short term, the following options are possible: • Reallocation of existing IPv4 addresses. This applies to the largest ranges allocated in the early years of the development of the Internet, most of whose address space is not used. True, it is not always possible to redistribute them, since it involves organizational and legal aspects, however some organizations (Stanford University, the US Department of Defense and some others) have already done so. In addition, in theory, regional registrars may require the LIR to use address space usage data in order to return unused blocks to the common pool. • Using NAT-technology providers. This is now common in some countries. However, this approach is associated with a number of inconveniences for the end user and is not always a convenient option; • Resale of IPv4 addresses. On the last paragraph we will dwell in more detail. Since IP addresses were always provided free of charge (although LIR pays membership fees), no one thought about whether they could be bought or sold. However, the harsh reality forced to consider and such an opportunity. The regional registrars regulations contain a corresponding clause regarding the redistribution of IP addresses between the LIRs. According to him, the organization that transfers IP addresses should justify the need for them just as in the case when a request for additional addresses occurs. The emergence of black market IPv4 addresses is already a reality. ICANN representatives themselves agreed that it exists and how to control it remains a question. Meanwhile, a platform appeared on the Internet for buying and selling and renting IPv4 addresses. According to brokers, the final cost of an IPv4 address ranges from 15 to 20 dollars.

Reasons for hosters to buy IPv4 address space now

IPv4 is the first major version of the protocol that is used to make a huge part of the Internet work. Of course, 4.3 billion IPv4 is quite a large number, but still it is not enough for all devices and needs around the world. IPv6 was developed to solve this problem. It uses a 128-bit address space. The total number of addresses will be 2 to 128 degrees, and it should be enough for many decades to come. And the only way to continue the development of the Internet is to use IPv6 addresses. However, this is now fraught with organizational and financial difficulties, which can be considered in a separate article. Despite the fact that almost all registrars gave available blocks, you can still buy and sell individual addresses. You can try to find the address ranges issued earlier, break into smaller blocks and distribute again. However, finding them is not easy, as their registry was not kept. One example is the MIT case. In 2017, MIT found that they had 14 million extra IP addresses that were not used. 8 million, it was decided to sell. However, this approach has a certain disadvantage. Uncontrolled bulk resale of IP addresses can lead to fragmentation of patterns and an increase in routing tables. This can cause problems in the work of routers with limited memory resources. Another solution is to use NAT. The NAT method allows you to convert the IP addresses of the transit packets: replaces the local address with the public one, writes it in the packet that goes to the web server, and returns it to the device. The largest number of NAT ports is 65,000, which means that the same local addresses can be turned into one public one. In this case, only the router is visible in the network structure, and the devices themselves are hidden. However, NAT has a number of drawbacks. For example, protocols that appeared before this method (for example, FTP) may work unstable via NAT. In addition, if all employees of the company decide to go to one site, the server can take it for a DDoS attack because the request is made from one public address and block access for all devices with this IP. Therefore, in terms of the fact that the widespread use of IPv6 will not soon make the decision to buy IPv4 address space for a hoster is now the most relevant.

Experts doubt in the need of transition to IPv6 until 2023

The crisis of free IPv4 addresses exhaustion divided the network community into two camps: conservatives, IPv4 supporters, and innovators actively promoting for IPv6. A representative of the leadership of Brocade, said that many customers of the company faced problems of migration to the new standard protocol. IPv6 is not compatible with IPv4, so for the transition it is necessary to replace the old equipment with new ones. Internet providers participating in the event promised that they would have at least 1% of IPv6 users connected to the launch date. Cisco and D-Link say their goal is to transfer all their products to IPv6 for routing. The transition from IPv4 to IPv6 may cause problems for some organizations, but large ISP and Internet companies, including Facebook and Google, have already invested a lot of power in IPv6 distribution. What it is all about? The IPv4 addressing scheme is limited to about 4.3 billion available addresses, most of which are currently assigned. For an exponentially growing fleet of devices connected to the Internet, the situation can turn into a serious problem and the inability of many global network subscribers to access the web. IPv6 should solve the problems, however, there were also opponents of this migration. Conservatives claim that the current addressing system can be used forever, the use of NAT will help, and there are no obvious prerequisites for the transition to Ipv6. Innovators believe that it is not economically feasible to continue to use old technologies, moreover, even the use of NAT cannot solve the problem completely. According to them, in the next 18 months, the Internet should fully switch to the use of IPv6. And although some manufacturers propose using both transport protocols at the same time, there are still many unresolved issues on this issue, the main one of which is the price of such a decision. Mr. Stewart said that Brocade has prepared a special NAT gateway for translating IPv4 to IPv6, which will help equipment that is incompatible with IPv6 hardware to function normally even after a full-scale transition. However, according to Brocade, more and more companies prefer IPv6.

The number of users using IPv6 to connect Google servers has reached 25%

According to Google statistics, the total number of IPv6 connections to the company's servers as for October 2018 exceeded 25%. Considering the mass nature of Google and the company's presence in all major markets except China, these statistics can be called moderately relevant and, on its basis, state that the world is gradually moving to IPv6 puncture with IPv4 which are seriously lacking. The most active countries in using the IPv6 protocol are Belgium (52.68%), Germany (39.14%), Greece (36.53%). The United States, India, Uruguay and Malaysia are a little behind this level. The most acute problem of reducing IPv4 addresses has become with the development of the market for IoT-devices that have a direct connection to the Internet, bypassing local routers and other access points. We are talking about smart home technologies, remote control devices and even gate relay control modules, which often use the mobile Internet instead of Wi-Fi technology. Also, devices with direct access to the Internet are ubiquitous in areas such as security and fire alarm systems, and use the SIM card of mobile operators as a communication module. Why is it so slow? IPv6 technologies are already more than 20 years old, but it began to receive obvious distribution only in the last five-year period, when providers faced the problem of lack of real IP addresses. The main reason to reject the implementation of IPv6 is the banal inertia of any network engineer and their motto: if it works, then it is better not to fix it. Due to optimization, in IPv6 packets, many things that do not directly affect routing were rendered in the extension header. This has significantly accelerated the work of the IPv6 network, but brought its own problems. Thus, the IPv6 architecture has generated new vectors for network and LAN attacks, which are guided by the same principles that were used for IPv4 networks. At the same time, IPv6 makes it difficult to control and monitor traffic, which, of course, does not suit providers that provide limited access to the network. In conclusion, it should be said that over the past ten years we have witnessed a massive preparation for the introduction of IPv6 and the transition to its immediate and widespread use. The vast majority of modern devices and operating systems support IPv6.

Thinking of buying IP addresses? Reasons to do it

Any computer connected to the Internet, have to be assigned a unique (in global terms) digital combination, called IP-address. This allows the various programs operating in the network, to work together to provide a single information space. That is why buying IP addresses is critical for those who working on the e-market, in the hosting industry or having a lot of devices in their internal infrastructure. Many can say that you can rent this resource. But you need to make sure than that you will receive own dedicated address. Principle issuing dynamic IP-addresses such that the issued address is assigned to the user as long as it is in the on-line connection to the server. If the user stops the connection and enters again, it will be assigned a computer has a new IP-address. Permanent same IP address does not change, it is called dedicated. Since the Internet network is growing very quickly, and address space is limited, the IP-addresses are used very sparingly, and now, as a rule, people are used to work scheme with time dynamic (per session) IP-address. For many users are buying IP addresses quite important. Dedicated IP-address can be used to create a stable secure connection for the exchange of information in the VPN, FIREWALL and others. Many hosting providers, Internet providers and data centers can offer you buying IP addresses service. Also, you should keep in mind that price of IPs are constantly growing: for 13-15% yearly. As well as growing price for the RIR membership. So if your company is definitely will need IPs it is better to buy it sooner. The advantages of buying IP addresses  - It provides secure access to your resources;  - Possibility of WEB-servers, mail and other servers on office computers;  - Possibility  of distributed corporate networks with remote access to them via the  Internet;  - The  ability to access the information resources with limited access  where  the user is identified by the IP-address
