Domain name

A domain name (or domain address) is a unique set of symbols that make up the address of a website, which can be used to find that website on the Internet (these are the symbols we type in the search bar of a browser after www).

A domain name is printed in Latin characters. It is important not to confuse a domain name with a postal address. A mailing address has an “@” symbol. It separates the domain name from the mailbox name. A website is located on a server under a digital IP address. And to match a specific IP address with a symbolic domain name of a website, there are DNS servers (DNS stands for Domain Name System).

As the modern Internet emerged, there was a need for a competent distribution of information on the network. This is how the domain name system emerged in the early 90s, allowing information to be distributed hierarchically. Thanks to the so-called “links”, people were able to “navigate” from one Internet page to another. It was a very convenient way to find the information they needed. Later, domains were created that reflected the activity of the site (educational, commercial, technical, etc.).

Domain name registration using the Cyrillic alphabet was first used in the .com and .net domains. Each domain name consists of levels separated by dots. There can be many levels, although you should limit yourself to two or three levels, as a very large domain name is inconvenient to use. The highest level (top-level) includes globally recognized domains such as .com, .org, .net, etc., known as top-level domains (TLDs). The lower level may include second-level domains, such as google.com, where .com is the TLD and “google” is the second-level domain. Domains can have a tiered structure that allows for unique identifiers for websites and other resources on the Internet.
