To identify the network address, find the decimal eqivalent of the octet. of hosts = (2^4)-2 = 14 because the network and broadcast address is not used. of subnets = 2^4 = 16 if ip subnet 0 is not allowed but you have to remove the first and last subnet giving you a total of 14 subnets. If you're given a /28, identify the masked bits (1) and unmasked bits (0). ![]()
