A Domain Name System (DNS) converts human-readable Internet Protocol (IP) addresses into the numerical addresses that computers use to find websites. The DNS regulates how IP addresses are used on the Internet.

DNS is a hierarchical structure of servers that convert human-readable names into IP addresses. The top level of the DNS is the Domain Name System root zone.

This zone contains the root servers that convert human-readable names into IP addresses.

When a user types in a human-readable name, the DNS converts it into an IP address. The DNS then sends the IP address to the computer.

The computer then uses the IP address to find the website.
