2.1.1 Domain registration. General issues

What is a domain name?

Domain name is a unique alphanumeric designation (including letters, numbers, the use of a hyphen “-” is allowed), which is a necessary element of an address on the Internet. A domain name allows you to identify a website or email address on the Internet. For example: thehost.ua, google.com.

Domains come in 1st, 2nd and 3rd levels. First level domains: for example, com, net, ua, etc. Under these domains there are second-level domains, for example, google.com or rambler.ua, third-level domains: banner.org.ua, soft.lviv.ua, etc. First-level domains are divided into two groups: territorial (ru, ua, de, us, etc.) and extra-territorial (com, org, net, etc.). The levels in the domain name are separated by a dot.

First-level domains are also called zones. For example, all domains of any level in the .UA geographical zone belong to Ukraine. You can register a second-level domain on any of the first-level domains.

When choosing a domain name, adhere to the following principles: brevity, ease of writing, informativeness and memorability. Plus a little imagination, a little knowledge about the industry in which you work or intend to.
