Fig. 4.1 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.
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 223.
address begins with the numbers 192 through 223.
The actual number of usable host IDs is smaller than the calculated number listed
above, because some addresses are reserved, by convention, for specific uses. See the
list in the next section, “Reserved IP Addresses.”
