The math behind subnetting
Article describing the math behind a subnet.
"This document will cover two quick ways for figuring out the numbers behind subnetting. The first way involves making a simple chart, the second way uses simple math that most people can do in their head, at least for smaller numbers. The first way is recommended for any exams, or times when you need to do a lot of subnetting quickly. The second way works best if you just need to know one or two examples, or to check your work from the chart." J!NX Forums - The math behind subnetting
