By far this is the part of networking that scares students.  However, it is not that scary.  You just need to understand binary math.  Oops I guess that is the scary part.  Well not any more.  Here are some tips and trick to make it easy.


A great book on the topic is "IP Subnetting made Easy!: A very simple and very clear guide to understanding IP subnetting that won’t leave you pulling your hair out." by John Kowalski.  It is only $2.99 for Amazon kindle format.
