A domain name such as digi1.co is a text given to a unique numerical address (IP). This IP points to Server which is hosting your website to serve public or private content. Domain Naming has to follow the rules of the Domain Name System (DNS). Every domain name has to be registered in the DNS.

A domain name has two parts, the main domain name, and the domain extension separated by a dot.

For example, In the domain name, digi1.co, digi1 is the domain name and co is the domain extension.
