If you want to be or are a network engineer or even in PC support you need to understand subnetting. The problem is, most of the so called IT experts make it so difficult to learn!
Subnetting Secret was written by somebody who read all the books and then threw them away and worked out the easy way to subnet. Sure, you learn the long way first using binary math but in the real world, for exams and technical interviews you need to be able to answer subnetting questions in about 20 seconds!

A great book that would help anybody who is looking to take their Cisco CCNA or CCNET exams.
This book mainly focuses on how to subnet a network in a cisco environment(or any networking environment for that matter) and will be a great study tool for you to use to pass any networking exams.
This book only cost £3.00 for my kindle which I would say is proper value for money.
