Home » Computer Networks » Computer networks miscellaneous » Question

An organization has a class-B network and wishes to form subnets for 64 departments. The subnet mask would be

1. 255.255.0.0
2. 255.255.64.0
3. 255.255.1.28.0
4. 255.255.252.0

Correct Option: D

Firstly, we should know, what a Class B network is and how is it different from Class A network and Class B network.
IP Address Class Network and Host Capacities

According to the formula number of subnets = 2ⁿ
So, the subnet mask would be = 11111111.11111111.11111100.00000000
255. 255. 252. 0
