 in the following format:
 nnn.nnn.nnn.nnn
 In a Class A network, the first of the numbers is the network number, the last three numbers
 are the local host address.
 In a Class B network, the first two numbers are the network, the last two are the local host
 address.
 In a Class C network, the first three numbers are the network address, the last number is the
 local host address.
 The following table summarizes the classes and sizes:
