class A supports maximum number of hosts. | | | | | <------network------><--------------------------------hosts------------------------------------>
The maximum number of host bits that can be borrowed from a class A address is 22 (technically you could borrow 23 but the resulting network would be useless). A class A address uses 8 bits for its network address and 24 bits for its host addresses. Class A uses a subnet mask of 255.0.0.0 You can only borrow 22 bits (instead of 24) because a valid network requires 4 addresses: A network address, two host addresses and a broadcast address. These networks would result in 30 bits used for the network address and 2 bits used for the host addresses. These networks use a subnet mask of 255.255.255.252
Class C network
The host information for a class C v4 address is in the last octet of the address.
A class ip address offer the most number of host
Class A
There are4 octets in an IP address as shown below:Octet1.Octet2.Octet3.Octet4Every IP class has different allocation of network and host ID.For class A, the network and host IDs' allocation is as follows:Network.Host.Host.HostFor class B, the network and host IDs' allocation is as follows:Network.Network.Host.HostFor class C, the network and host IDs' allocation is as follows:Network.Network.Network.HostYou may go to the following link get more info on IP address classes and their IDs:www.iphow.x10hosting.com
An example of a valid class C address would be 192.168.6.200

A class C address.
This address is for a class B network (128 - 191)
