What is DNS in Simple English?

Published in: google dns - opendns - Video of the Day

You type a web address – say www.youtube.com - in the web browser, your computer queries a DNS server to find the corresponding IP address where that site is located and once it has that information, it routes your browser to the correct website.

That is a simplified definition of DNS but, behind the scenes, several parties could get involved as soon as your computer asks for the IP address of a domain name. There’s the Resolving Name Server, the Root Name Server, the TLD Name Server and finally the Authoritative Name Server.
