NETWORKS
Addresses
Each device on the network has a unique
address. This allows you to communicate with a
specific computer (or other device, such as a
printer). That way, your e-mail doesn't go to
everybody, and your print job doesn't get
printed simultaneously on all printers on the
network.
There are several addressing schemes for
networks. Of these, the most popular is that of
the Internet Protocol (IP). In addition to being
used on the Internet, IP addressing can also be
used for standalone networks that don't connect
to the Internet. The network addresses shown in
the illustration are sample IP addresses.
Other network addressing schemes you may
encounter include IPX (used with Novell
NetWare networks), DLC, and AppleTalk. In this
tutorial, we limit our discussion of network
addressing to IP addressing, as it is the most
popular.
The number of possible IP addresses is huge. So
is the number of Internet users, and the
possibility of conflicts is a real one. If you use IP
addresses on your LAN and that LAN connects
to the Internet, you must be careful to use
addresses that have come from a reliable source,
such as your Internet service provider (ISP).
