How many hosts can you have with a subnet of 192.168.1.0/28?

A) 30
B) 14
C) 16
D) 6


B
Explanation: The binary representation of /28 prefix is 11111111.11111111.11111111.11110000. The formula to determine the number of hosts is 2 ^ X - 2, where X is equal to the number host bits available for host addressing. In this case, there are 4 bits that are not being used for the network address and are available for host addressing. (2 ^ 4 - 2 = 14); therefore, there are 14 possible hosts.
