Domain Name System (DNS) Server
A computer server that hosts a network service for offering a response to queries is called a name server. It maps either an addressing component or numeric identification. This is done by the server to give a response to a network service protocol request.
DNS servers mainly translate domain names and hostnames into the corresponding numeric Internet protocol address (IP address). DNS also helps to recognise a namespace of the Internet, used to identify and locate computer systems and resources on the Internet.
There are 13 important DNS root servers on the internet that store a complete database of domain names and their associated public IP addresses. These top-tier DNS servers are named A through M for the first 13 letters of the alphabet. Ten of these servers are in the US, one in London, one in Stockholm and one in Japan.
