The following table shows class C IP address last octet values for each subnet.

The following table is a summary for class “C” subnet planning.

Subnetting With Class A and Class B Networks.

For class “A” and class “B” addresses the subnet mask also determines which bits are part of

the network number and which are part of the host ID.

A class “B” address has two host ID octets available for subnetting and a class “A” address has

three host ID octets (see Table 45 on page 150) available for subnetting.
