When determining the number of subnets you will have, why must you subtract two from the total that appears to be possible, based on the number of bits you have borrowed from the host IDs of a Class network address?
What will be an ideal response?
You must always subtract two subnets because you cannot have a network ID extension of all zeroes (reserved for the network itself), nor can you have a network ID extension of all ones (reserved for the broadcast address).
