where n is a number from 0 to 255, inclusive. This form is referred to as decimal dot notation
or dot notation.
Table 7-4 lists the number of networks and nodes and the address ranges for Class A, Class B,
and Class C networks. Class D networks are described later in this chapter in “IP Multicast
Addresses.”
To determine a network address and host address from an internet address, you must
separate the network and host address fields. For example, the bit representation of internet
address 192.6.1.1 is separated as follows:
Figure 7-2 Bit Representation of Internet Address
Assigning an Internet Address
Each node on the network has at least one internet address. When assigning internet
addresses, you must determine network addresses and host addresses as described in this
section.
