It is recommended that you choose private network IP Addresses from the above list. For

more information on address assignment, refer to RFC 1597, Address Allocation for Private

Internets and RFC 1466, Guidelines for Management of IP Address Space.

Subnet Mask

In the absence of subnetworks, standard TCP/IP addressing may be used by specifying subnet masks as shown

below.

IP Class Subnet Mask

Class A 255.0.0.0

Class B 255.255.0.0

Class C 255.255.255.0

Subnet mask settings other than those listed above add significance to the interpretation of bits in the IP address.

The bits of the subnet mask correspond directly to the bits of the IP address. Any bit an a subnet mask that is to

correspond to a net ID bit in the IP address must be set to 1.
