When referring to an Internet address or name a domain or domain name is the location of a website. For example, the domain name “google.com” points to the IP address “188.8.131.52”, but it is generally easier to remember a name rather than a long string of numbers. A domain name can be a maximum of sixty-three characters with one character minimum, and is entered after the protocol in the URL, as you can see in the following example.
What was the first domain?
The first Internet domain name “symbolics.com” was registered by Symbolics, a Massachusetts computer company on March 15, 1985.
When deciding on a domain name, its a good idea to keep it simple, something that is easy to remember.
