IP Subnetting made Easy!: A very simple and very clear guide to understanding IP subnetting that won’t leave you pulling your hair out.

Now, over 7,000 copies in circulation!

I originally developed this book for my networking students at the community college where I teach and it is at their urging that I decided to publish this book. Since then, thousands of copies have gone out and the book has been adopted at several other colleges and schools. Students everywhere have loved the book over the years and I know you will too. You will finally be comfortable subnetting on certification tests and can recreate – from memory – my cheat sheet which allows you to solve subnetting problems in seconds (yes…seconds). No complex charts to remember….no “tricks”…no gimmicks. I’ve successfully taught my method to hundreds of students. It’s proven and it works.
