A Domain Name System, or DNS, is what it's called. In its most basic form, a DNS is a list of domain names that correspond to IP addresses. They bridge the gap between computer and human language, ensuring that both servers and people are satisfied.

Recursive resolvers, root nameservers, TLD nameservers, and authoritative nameservers are the four servers that work together to send an IP address to the client in a normal DNS query without caching.

The Domain Name System (DNS) converts human-readable domain names (such as to machine-readable IP addresses (for example, 192.0. 2.44).

  • Log in to Google Domains on your computer.

  • Select Custom from the drop-down menu at the top of the page.

A domain is in charge of governing basic functions, such as access control, authentication, and so on. A server's job is to distribute network resources and rights to other network clients.
