IP Addressing 1 Networking Overview
Administration for Network Connectivity
CID: 77730 555-233-504 — Issue 1 — April 2000

The other four possible subnetting schemes for Class C addresses, using 2, 4, 5, and 6
subnet bits, are formed in the same way. Which of the 5 subnetting schemes to use
depends on the requirements for the number of subnets and the number of hosts per
subnet.
Class-A and Class-B
subnets
For Class A and Class B IP addresses, subnets can be formed in the same way as for
Class C addresses. The only difference is that many more subnets per network can be
formed. For Class B networks, subnets can be formed using from 2 to 14 bits from the
3rd and 4th octets. For Class A networks, subnets can be formed using from 2 to 22
bits from the 2nd, 3rd and 4th octets.
The Subnet Mask field on the ppp Data Module screen (used for ppp connections) and
on the IP Interfaces screen (used for ethernet connections) enables the specification of
a subnet for the IP address.
