Domain lookup system and how use it

Domain is the name for the site. Agree that it is more convenient to use mysite.com than the IP address 108.162.192.0. And besides, imagine the situation. You placed the site on the hosting server and received the IP address. But, moving to another hosting IP will change, which will cause a disaster. But in the case of domain names this will not happen. Why?

The fact is that there are thousands of DNS servers on the Internet that will state that the ktonanovenkogo.ru domain is accessible at the IP address 108.162.192.0. If I move to another hosting, I’ll go to the panel of the domain name registrar, change something, and in all Internet DNS servers it will be written that the site ktonanovenkogo.ru needs to be searched for already at another IP address. Is it convenient after all?

Convenient, but probably not yet clear. The main thing to understand is that the name for the site is a very important thing and it is for life. As you call a boat, it will float. True, it is important not only the name, but also the level of the domain, as well as the zone to which it belongs. Again incomprehensible? Well, let's do it in order.

How a domain name works

Let's start with the basics. The domain record (site name) should include all levels of nesting of the domain (all zones into which it belongs) so that it is unique and there is no confusion. For example, you can’t just write “mysite” - you need to specify the domain zone to which this domain belongs - “mysite.com”.

There are two basic rules for writing domain names:

The zones that this domain belongs to are listed from right to left.

Dots are used as a separator.

How and where can I register a domain in top-level zones

Second-level domain names simply can’t be obtained, as a rule (and it’s better not to try, because the name for the site is too important to register with it is not clear to anyone). They cost money. Moreover, payment is made for the year, and then the domain must be renewed.

Such companies are not so many, but they can have a whole network of resellers who will deal with the selection and sale of domains on their behalf. If the current reseller didn’t satisfy you with something or you had strains with it, then, contacting the registrar, you can choose another reseller or go directly under the registrar’s wing.

Without any restrictions, you can buy domains in the public zones .com, .net, .org, .info, .biz and .name. In the zones .edu, .gov and .mil, such an opportunity is provided only for institutions, as well as state educational and military institutions. There are also a number of specialized first-level domains, for example, .travel, .jobs, .aero, .asia.

Second-level domain names in these public zones can be bought from any registrar (not only national), which, in fact, is used by some resources that may conflict with copyright holders. The same torrents were forced to move to the public zone org, because in the national domain zone ru its resource was blocked.
