<variant> The number of bits used to identify nodes depends on the class of the network.

<variant>3 out of 5 address classes are reserved for multicast and experimental use.

<variant> Reading the first bit allows you to determine the class to which the address belongs.

<variant> The host portion of a class C address can be up to 24 bits.
