10.5.1 WAN IP Address Assignment
Every computer on the Internet must have a unique IP address. If your networks are isolated
from the Internet (only between your two branch offices, for instance) you can assign any IP
addresses to the hosts without problems. However, the Internet Assigned Numbers Authority
(IANA) has reserved the following three blocks of IP addresses specifically for private
networks.
You can obtain your IP address from the IANA, from an ISP or have it assigned by a private
network. If you belong to a small organization and your Internet access is through an ISP, the
ISP can provide you with the Internet addresses for your local networks. On the other hand, if
you are part of a much larger organization, you should consult your network administrator for
the appropriate IP addresses.
"
Regardless of your particular situation, do not create an arbitrary IP address;
always follow the guidelines above. For more information on address
assignment, please refer to RFC 1597, Address Allocation for Private Internets
and RFC 1466, Guidelines for Management of IP Address Space.
