WHAT IS A DOMAIN NAME:
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: boxbutte.net mail.boxbutte.net
workshop.boxbutte.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 (boxbutte.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. In these cases, some real Internet machine must handle
the mail on behalf of the listed Domain Name. |
