GATE | GATE-IT-2004 | Question 26
A subnet has been assigned a subnet mask of 255.255.255.192. What is the maximum number of hosts that can belong to this subnet?
Explanation: The given subnet mask, 255.255.255.192, in binary is- 11111111.11111111.11111111.1100000
Number of bits for the network prefix is- 8 + 8 + 8 + 2 = 26
Number of bits avaiable for hosts – 32 – 26 = 6
Number of addresses available =
The first address is reserved for the subnet and the last address is reserved as the broadcast address.
So, number of host addresses = 64 – 2 = 62
Therefore option (C) is correct.
