to calculate the number of host, the equation is 2^Y-2 where y in the number of host bits
to calculate the number of subnets, the equation is 2^X-2 where x is the number of network bits.
trouble is that some articles say 2^x-2 and some say 2^X to calculate the number of network bits.
i cannot for the life of me find out which is supposed to be correct, as each approach makes NO reference to the other approach.
i was always taught 2^x-2
any opinions, thoughts?
