1. Defining IP ranges

You can define as many IP ranges a you needed. An IP range has the form start-limit. Here are some IP ranges for different network types.

192.168.1.1-21

This defines the first 21 IP numbers of the class C network 192.168.1.0.

172.16.0.1-2.254g

This defines a huge range in a class B network. Note that this notation won't be used much. This kind of network is often split into several physical networks, so IP number are allocated. This is one place where the "IP range definitions" system is very useful.
