What is Domain
Domain name is the identity of one or more IP addresses, i.e. the domain name google.com points to the IP address "126.96.36.199". It is easy to remember a name rather than a long string of numbers.
A domain name cannot have more than sixty-three characters excluding .com, .net, .org, .edu, etc. The minimum length of a domain is one character excluding the extensions. It is entered in the URL after the protocol and subdomain as shown in the following example and the image:
https: ( Protocol)
google.com (domain and domain suffix)
