Overview

Name servers (NS) are the repositories of information that make up the domain database. The database is divided up into sections called zones, which are distributed among the name servers. The most important function of DNS servers is the translation (resolution) of human-memorable domain names (example.com) and hostnames into the corresponding numeric Internet Protocol (IP) addresses (93.184.216.34), the second principal name space of the Internet, which is used to identify and locate computer systems and resources on the Internet.

When searching for a domain name, it hits the name server, which translates the domain name into the Internet Protocol (IP) address, so that the browser can locate it. Once it’s found the domain name in the name server, web browser uses the IP address to connect to the server and load the requested site.
