TCP/IP addresses are divided into classes based on the network’s
size. The TCP/IP address assigned depends on the class and includes
the network ID and the host (individual computer or peripheral) ID.

Fig. 5.19 Network Addresses
The class A address is used for large networks with more than
65,536 (2
16
) individual workstations. The first 8 bits of the address
identify the network. The remaining 24 bits are used as host IDs. The
class A address begins with the numbers 1 through 126.
The class B address is used for networks with more than 256 (2 8 ), but
less than 65,536 (2 16 ) workstations. The first 16 bits identify the
network. The remaining 16 bits are used as host IDs. The class B
address begins with the numbers 128 through 191.
The class C address is used for networks with less than 256 (2
8
)
workstations. The first 24 bits identify the network. The remaining 8
bits are used as host IDs. The class C address begins with the
numbers 192 through 254.
