What is Domain Name System
A Domain Name System (DNS) is a hierarchical name system for domains and IP addresses . It includes a distributed and scalable database.
The Domain Name System distributes the task of assigning domain names, mapping domain names to IP addresses, and assigning domain name servers (DNS Servers) to each domain. Name servers not only looks for assigned domains but also in turn can assign other authoritative name servers for their sub-domains. This makes Domain Name System (DNS) distributed.
As the network grows, Domain Name System (DNS) is required to be more scalable so that it can record a change in a host's address in place. Other hosts would learn the change dynamically through a notification system . To know on how to install DNS follow the link Install DNS.
