OOOOHH! OK Thanks!

Hey Shkuey!
That seems simple enough when you break it down like that but I guess the problem that I am having is that say I get a test question that asks how many possible IP addresses can you get from 132.64.0.0/16? Well I know that is a class B network and that there a possible 65,534 IP addresses in a class B. But how do I do the math to say what the exact number of IP's are? Is the process to find the SN ID, then the smallest host ID, then the largest host ID or is there something simpler that I am missing?
