DNS Server is a computer program or a set of instructions that allows computers to find their way to other computers on the network, by translating human-readable domain names (like www.google.

com) into IP addresses.

A DNS server is usually located on a publicly accessible network, and is used to translate domain names into IP addresses. When a user types in a domain name (like www.

google.com), the DNS server will look up the corresponding IP address.

DNS servers are essential for the functioning of the Internet. Without DNS, users would have to type in each website’s domain name (like www.

com) each time they wanted to visit it. DNS servers allow users to access websites by simply entering their IP address.
