What is DNS?

Applies to: Domain Names

In simple terms, the Domain Name System (DNS) is an "Address Book" used to map a human friendly domain name (e.g. lcn.com) to a computer readable IP address (e.g. 94.126.40.226), which can then be used to locate and communicate with that computer.

Using DNS is similar to making a phone call with your mobile phone. Your phone dials the number for you and the telephone network uses that number to connect you.
