254 - a class C subnet uses 8 bits for the hosts and 0 and 255 are reserved.

The maximum number of hosts per class B network is 65536.

In Class A networks, the maximum number of hosts is calculated as (2^{24} - 2), which equals 16,777,214 hosts. This formula accounts for the network and broadcast addresses, which cannot be assigned to hosts. Class A networks use the first octet for the network identifier, allowing for a large number of hosts within a single network. However, not every Class A network will have the maximum number of hosts; it depends on the specific subnetting used.
Each network supports a maximum of 16,777,214 (2 24 -2) hosts per network
The number of possible IP address decreases as one steps down from Class A to Class C IP addresses because the availability of usable hosts. There is a decrease in the number of usable hosts from Class A to Class C IP addresses.

A class ip address offer the most number of host
Class A, B and C Based on the split of the 32 bits, an IP address is either Class A, B or C, the most common of which is Class C. More than two million Class C addresses are assigned, quite often in large blocks to network access providers for use by their customers. The fewest are Class A networks, which are reserved for government agencies and huge companies. Although people identify the class by the first number in the IP address (see table below), a computer identifies class by the first three bits of the IP address (A=0; B=10; C=110). This class system has also been greatly expanded, eliminating the huge disparity in the number of hosts that each class can accommodate (see http://www.answers.com/topic/cider).

The host bits are further divided between subnets and hosts. See subnet mask.

Class A
The maximum number of hosts that can be served by an IP address depends on the subnet mask used. In IPv4, a typical subnet allows for 2^n - 2 hosts, where n is the number of bits available for host addresses (the total bits minus the bits used for the network). For example, a /24 subnet (255.255.255.0) provides 256 addresses, allowing for 254 usable hosts. In IPv6, the address space is vast, allowing for an effectively unlimited number of hosts due to its 128-bit structure, providing 2^128 possible addresses.
