If it’s unlikely that your local area network will ever be connected to the Internet and you
want to use TCP/IP as the protocol for transmitting information on your network, it’s possible
to set up a “private” TCP/IP network. When you set up a private network, you choose IP
addresses from the blocks of IP addresses that the IANA (Internet Assigned Numbers
Authority) has reserved for private intranets:
m 10.0.0.0–10.255.255.255 (10/8 prefix)
m 172.16.0.0–172.31.255.255 (172.16/12 prefix)
m 192.168.0.0–192.168.255.255 (192.168/16 prefix)
If you set up a private TCP/IP network, you can also provide DNS service. By setting up TCP/IP
and DNS on your local area network, your users will be able to easily access file, Web, mail, and
other services on your network.

Important If you think you might want to connect to the Internet in the future, you should
register with an Internet registry and use the IP addresses provided by the registry when
setting up your private network. Otherwise, when you do connect to the Internet, you’ll
need to reconfigure every computer on your network.
