NOTE When specifying internet addresses, do not use leading zeroes within address
fields. For example: 192.006.012.023 is incorrect; 192.6.12.23 is correct.
Assigning Network Addresses
To assign network addresses, follow these rules:
• You must have a network address for each logical network.
• If your system is attached to more than one physical network via a gateway, the network
addresses of these interfaces may not be the same. Refer to Table 7-3 below for a gateway
example.
• All nodes in the same network, however, must have the same network address.
• Do not assign the network addresses 0 or 255 (Class A), 0.0 or 255.255 (Class B), or 0.0.0
or 255.255.255 (Class C) to any network. Those addresses are reserved.
• Do not assign Class A network address 127. This address is reserved for the loopback
interface.
