In classfull addressing schemes each address class limited the total number of clients per network. Other than that, there are no particular functions for each address class.
Class B, if you are referring to classful addressing schemes.
192.168.0.254 is a valid "class C" IP address.
There are five IP classes that IP addresses are divided into. The IP address 185 is a class B address. Class B IP addresses have the first three numbers of 128 to 191.
Class C
The First Octet is used to derive the Class of an IP address...... Eg: 192.168.1.1------ The IP class for this IP add is CLASS "C" as the first Octet is 192.
Class a
Class C address
class B
Class B
It belongs to the class A.
This is a class C address. This class ranges from 192.0.0.0 to 223.255.255.255
An example is 10.0.0.1. An IP address consists of four numbers, separated by dots (so there are three dots in total). Since each of the number represents a byte (or "octet"), each of these numbers is in the range from 0 to 255. Any IP address in which the first of these four numbers is in the range from 0 to 127 is considered to be a "Class A" address. (In the binary representation, that means that the first bit is equal to zero.)
