How do you calculate the number of hosts per subnet given a subnet mask? (Note: 2^y means 2 to the y power. - CORRECT ANSWER-(2^y)
minus 2 where y is the number of 0s in the subnet mask
The number of hosts is (2^y) minus 2 where y is the number of 0s in the subnet mask. So, 1 subnet bit (first octet 100000000 or 128.0.0.0) means
(2^31) - 2 = 19,999,999,999,999,999,999,999,999,999,998 hosts. 2 subnet bits (first octet 110000000 or 192.0.0.0) means (2^30) - 2 =
1,999,999,999,999,999,999,999,999,999,996 hosts. 3 subnet bits (first octet 111000000 or 224.0.0.0) means (2^29) - 2 =
199,999,999,999,999,999,999,999,999,996 hosts.
How do you calculate the number of subnets given a subnet mask? (Note: 2^x means 2 to the x power.) - CORRECT ANSWER-2^x where x is
the number of 1s in the subnet mask
