The Domain Name System (DNS) translates human-readable domain names, such as www.example.com, into the numerical IP addresses that computers use to locate and communicate with each other on a network. Without this service, users would have to remember and enter IP addresses directly, which would be impractical for everyday use. The translation service functions like a phonebook for the internet: names are looked up to find their corresponding numbers.
