We wrote this book because we came up with a better way to explain how to subnet. Guaranteed. For you network engineers, TCPIP network addressing is not just about subnetting anymore. It's about classless addressing, which includes subnetting, variable subnetting (VLSM), supernetting, and Classless Interdomain Routing (CIDR). You simply won't find a more thorough explanation ofclassless addressing than our Ultimate Guide to Subnetting!  Learn more

All of these training guides are part of our "e-Guide" series. e-Guides are concise, low cost, well researched training materials delivered in electronic format (Adobe Acrobat PDF). But please don't think of these materials as anything less than "bookstore quality". We simply take advantage of current technology to mitigate the issues of publishing and fulfillment lead times. You benefit from knowing that you’ll receive the very latest fruits of our labor. And since the printing company and middleman are cut out, the prices are far lower than bound books.

All e-Guides are painstakenly researched to minimize errors. Each e-Guide is authored by the same individual. The emphasis is on quality not quantity. This is not just a slogan. We were inspired to create these guides when we saw so many potentially good computer books falling short of the mark because they had been rushed to the book stores due to competitive concerns.

All of our e-Guides come with a no-risk, 100% satisfaction guarantee. We hope you will enjoy reading them as much as we did creating them. Be sure to view the testimonies from our readers. Thank you.
