Do the octets in a subnet mask have to be 255? Can it be, for example, 252? I thought they were always 255.
"If you have cable, open your PC's command prompt, type ipconfig, and check out your subnet mask. It's probably a /20 or /21 Class B address—yikes! You already know that translates to either 4,094 or 2,046 hosts per cable network connection. Definitely not good."

Concerning the above statement, how would you know how many hosts there are?
