Domain Name System

The Domain Name System (DNS) is an Internet service that serves as a directory or "phone book" for network communication. It translates human-readable domain names (such as example.com) into the numeric IP addresses required by host machines to locate and communicate with each other, eliminating the need for users to memorize numerical addresses.
