What is Domain Name?
Domain name is the unique name that identifies an Internet site. Domain Names always have 2 or more parts, separated by dots. The part on the left is the most specific, and the part on the right is the most general. A given machine may have more than one Domain Name but a given Domain Name points to only one machine. For example, the domain names: domainname.net mail.domainname.net can all refer to the same machine, but each domain name can refer to no more than one machine.

Usually, all of the machines on a given network will have the same thing as the right-hand portion of their Domain Names (domainname.net in the examples above). It is also possible for a Domain Name to exist but not be connected to an actual machine. This is often done so that a group or business can have an Internet e-mail address without having to establish a real Internet site.
