Does IP Subnetting boggle your mind? Would you like a “cheat sheet” to have around?

If so, we have got some great subnetting charts for you!

In chart #1, we take a network from each of the three classes (A, B, and C) and calculate the number of hosts and networks for every possible subnet mask. Here it is:

In chart #2, we calculate every possible subnetting variation for a class B and C network. Take a look:

For lack of a fancy IP subnetting calculator, these are great subnetting references to have around.

Enjoy!
