This chapter provides information on the System screen.

Every computer on the Internet must have a unique IP address. If your networks are isolated

from the Internet, for instance, only between your two branch offices, 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.

10.0.0.0

172.16.0.0

192.168.0.0

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.

Similar to the way houses on a street share a common street name, computers on a LAN share

one common network number.
