How did domain names appeared and why?

When the Internet first appeared, there were no domain names. Computers had digital names - IP addresses. To connect to another computer, you needed to know its IP address. For example, 216.58.215.110 is one of the addresses of YouTube. Computers do not care, but it’s difficult for a person to remember one such figure. Therefore, people came up with textual names. By the same logic, we create contacts in the phone - so that you do not have to memorize a bunch of numbers.

With the development of the network, adding names manually has become inconvenient. They decided to automate the process and came up with domain names - the technology that we still use.

Why do we need domain zones

A domain zone is a part of a domain that comes after a dot. As an extension of files on a computer.

The first domains appeared in 1985. Then there were seven domain zones:

.com - for commercial sites;

.net - for network structures;

.org - for non-profit organizations;

.edu - for educational institutions;

.gov - for government organizations;

.mil - for military organizations;

.arpa - for the Internet infrastructure.

How domain zones differ from each other

Different domain zones have different registration requirements. For example, most common domains like .com, .net, or .org can be registered by anyone. It doesn’t matter which site will be on the domain: commercial or non-commercial, personal blog or corporate website, forum or online store.

But for some common domain zones there are still limitations. For example, only educational institutions can register a domain in the .edu zone. When registering, you will have to send documents on accreditation of a school or university.

Most national domains have special requirements. Most often, such a name can be registered only by a citizen of the state: when registering, you must specify the address inside the country, the number of the passport or driver’s license.
