What is the difference between class a and class b address in network?

Answer 1

A class C network has a subnet mask of 255.255.255.0 and can have 254 IP addresses, for example from 192.168.0.1-192.168.0.255 A class B network has a subnet mask of 255.255.0.0 and can have 255 X 254 IP addresses, for example from 192.168.0.1 - 192.168.255.255

Answer 2

Network classes are all about the subnet mask. Class A networks have a subnet mask of 255.0.0.0, Class B 255.255.0.0, Class C 255.255.255.0. The subnet mask determines the portion of the ip address that is the network portion (i.e. what network it is on, like the 192.168.3.0 network for a class C mask), and the portion that is for the node (like the x.x.x.1-254 for a class C mask). So, a Class A network has a 255.0.0.0 subnet mask, and uses the first octet for the network address, and the last 3 octets for the node address, while a class B network has a 255.255.0.0 subnet mask, and uses the first and second octet for the network address, and the last 2 octects for the node address. Class A networks then have more available node ip addresses per network, while a Class B network has fewer node ip addresses per network, but then has more possible network id's.

Answer 3

No real advantage to any of them, they are just the size of the address space:

C = 256 (xxx.xxx.xxx.0-255)

B = 256 x 256 (xxx.xxx.0-255.0-255)

A = 256 x 256 x 256 (xxx.0-255.0-255.0-255)
