IP addressing overview
IP address classes
IP addressing uses a 32-bit address to identify each host on a network. To make addresses easier to read,
they are written in dotted decimal notation, each address being four octets in length. For example,
address 00001000000000010000000100000001 in binary is written as 10.1.1.1.
Each IP address breaks down into two parts:
• Net ID: Identifies a network. The first several bits of a net ID, known as the class field or class bits,
identify the class of the IP address.
• Host ID: Identifies a host on a network.
IP addresses are divided into five classes, shown in Figure 4 . The shaded areas represent the address
class. The first three classes are widely used.

Table 1 describes the address ranges of these five classes.
