Chapter 13 Analyzing Subnet Masks

This chapter covers the following exam topics:

1.0 Network Fundamentals

1.6 Configure and verify IPv4 addressing and subnetting

The subnet mask used in one or many subnets in an IP internetwork says a lot about the intent of the subnet design. First, the mask divides addresses into two parts: prefix and host, with the host part defining the size of the subnet (that is, the number of hosts in the subnet). Then, the class (A, B, or C) further divides the structure of addresses in a subnet, breaking the prefix part into the network and subnet parts. The subnet part defines the number of subnets that could exist inside one classful IP network, assuming that one mask is used throughout the classful network.

The subnet ...
