Obtaining a Registered IP Address | 3Com 3 instruction

86APPENDIX C: IP ADDRESSING

192.168.100.X (where X is a number between 1 and 254) with a subnet mask 255.255.255.0. If you are using SLIP, use the default SLIP address of 192.168.101.1 with a subnet mask of 255.255.255.0.

These suggested IP addresses are part of a group of IP addresses that have been set aside specially for use “in house” only.

CAUTION: If your network has a connection to the external IP network, you must apply for a registered IP address. This registration system ensures that every IP address used is unique; if you do not have a registered IP address, you may be using an identical address to someone else and your network will not operate correctly.

Obtaining a Registered IP Address

InterNIC Registration Services is the organization responsible for supplying registered IP addresses. The following contact information is correct at time of publication:

World Wide Web site: http://www.internic.net

Advanced Overview IP addresses are 32-bit addresses that consist of a network part (the address of the network where the host is located) and a host part (the address of the host on that network).

Figure 26 IP Address: Network Part and Host Part

IP Address	32 bits

network	host

The boundary between network and host parts depends on the class of IP network.

IP addresses differ from Ethernet MAC addresses, which are unique hardware-configured 48-bit addresses. A central agency, such as the InterNIC Registration Services mentioned above, assigns the network part of the IP address, and you assign the host part. All devices that are connected to the same network share the same network part (also called the prefix).
