« Back to Domain Name Dictionary | Definition of DNS
DNS is an acronym for Domain Name System.
The Domain Name System (DNS) helps users to find their way around the Internet. Every computer on the Internet has a unique address – just like a telephone number – which is a rather complicated string of numbers. It is called its “IP address” (IP stands for “Internet Protocol”). 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 207.151.159.3, you can type www.internic.net. It is a “mnemonic” device that makes addresses easier to remember.
