The module considers two types of network addresses – MAC addresses and IP addresses

The module considers two types of network addresses – MAC addresses and IP addresses. There is also a third kind called symbolic domain names. The Domain Name System (DNS) is responsible for resolving the IP address to the domain name and vice versa. Find information about domain names yourself – what parts they consist of, examples

The domain name of the site is used so that it is not necessary to remember the digital IP-addresses, since it is much easier to remember the name of the site, say yandex.ru, and not its IP address 77.88.21.11. A domain name consists of several parts separated by periods. The individual parts of the name are different domains, which include the site name, and domains are numbered from right to left.
