A Domain Name Server (DNS) is a computer server that contains a database of public IP addresses and associated host names. In most cases, DNS serves to resolve, or translate, those common names to IP addresses as requested.

The Domain Name System. translates Internet domain and host names to IP addresses and vice versa.
It is very difficult to keep in mind the IP addresses of all the websites we visit daily. Words are easier to remember than strings of numbers. This is where domain names come into the picture. When you visit a website, all you need to know is its URL.
