Basically, Classless IP addressing means that the IP address and the SUBNET mask of the device can belong to different classes i.e. A, B or C.
For example: IP Address is Class B while SUBNET is Class C
Class A: 1-126
Class B: 128-191
Class C: 192-223
i.e.: 192.168.1.1 is a class C IP address
Class A: 255.0.0.0
Class B: 255.255.0.0
Class C: 255.255.255.0
