DNS: Domain Name System
Domain Name System or Service (DNS) is a distributed Internet directory service. DNS is used mostly to translate between domain names (www.domainname.com) and IP addresses (123.123.123.123), and to control Internet email delivery. Most Internet services rely on DNS to work, and if DNS fails, web sites cannot be located and email delivery stalls.
