If a class B network on the Internet has a subnet mask of 255.255.248.0, what is the maximum number of hosts per subnet?

1. 1022
2. 1023
3. 2046
4. 2047

Correct Option: C

As we have the Subnet Mask 255.255.248.0 i.e., 255.255.11111100.00000000
where 1 represents the network portion and 0’s represent the host.
So, the number of host = 2ⁿ
Where n = no. of 0s.
So, the number of host = 2¹¹
So, the number of host = 2046
