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

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.

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)
