Address Type
Local Host
Because IP addresses must be unique all over the world, you cannot just select random
addresses. There are three address domains to use if you want to set up a private IP-
based network. These cannot get any connection from the rest of the Internet, because
they cannot be transmitted over the Internet. These address domains are specified in
RFC 1597 and listed in
Table 17.3 Private IP Address Domains
Network/Netmask
10.0.0.0/255.0.0.0
172.16.0.0/255.240.0.0
