What is the Internet domain name system?
The Domain Name System (DNS) enables users to find their way around the Internet. Every computer on the Internet has a unique Internet Protocol (IP) address – just like a telephone number – which is a rather complicated string of numbers and IP Addresses are hard to remember. The DNS makes using the Internet easier by allowing a familiar string of letters (the “domain name”) to be used instead of the arcane IP address. So instead of typing an IP Address such as 207.151.159.3, you can type www.internic.net into your browser address bar..
