The result of over three years' work by the author of the widely acclaimed electronic resource The PC Guide, The TCP/IP Guide breaks new ground in technical education, combining understandable text with numerous examples, over 300 full-color illustrations, and numerous ease-of-use features. It is distributed in electronic (PDF) form, resulting in numerous benefits: up-to-date content, lower cost, immediate availability, thousands of hyperlinks between related topics, and instant text search. The TCP Guide is ideal for anyone who wants to really understand how TCP/IP works, including educators, students, networking professionals, and those working towards certifications.

The full TCP/IP Guide is over 1,600 pages long and is available to license for a low fee, with discounts for multiple orders. The material is also available online, absolutely free. And now, it is also available as a print book!
 

• Hello: Wow, it has been a while since I updated this! And I know that the material has also gotten rather old at this point. I've had a lot of people ask me about updating The TCP/IP Guide, and this is something I've been wanting to do for years. Unfortunately, for a variety of reasons, it is unlikely that this will happen.
  
  There are a number of reasons for this, some having to do with my personal life and the needs of my family, and some having to do with the marketplace and how people prefer to find and consume information these days. (Hint: It's not in 1,600 page print books.) This isn't ideal for anyone, but unfortunately I have no choice, as it simply isn't practical for me to undertake this sort of project at this stage of my life and career. I hope you all understand, and continue to find the existing material useful going forward. (In truth, while a lot has changed, many of the fundamentals are actually pretty similar to how they were 15 years ago.)
• End of Direct Book Sales: In a related move, I am discontinuing direct sales of the hardcover book. Orders of the book sent to me directly have dwindled, and each one required me to pack and ship the book individually, a time commitment better spent in other areas. I continue to sell the download edition, and of course the book can still be purchases at places like Amazon.
• General Site Updates: I've updated several pages on this website to reflect the end of book sales and to modernize some of the text (like removing references to 56k modems!)

• Happy New Year and Changes to TCP/IP Electronic and Book Sales: I have made some significant modifications to the front end of the website (the part you're reading now, that is, not the content) to reflect changes in how I am selling The TCP/IP Guide going forward. Specifically:
  • I am no longer selling The TCP/IP Guide in CD form. This option was never very popular, and has become even less so as high-speed Internet access has become universal. Having the various CD options was confusing, and to top it off, I've also run out of the pressed CDs I ordered years ago, so I've just eliminated this option.
  • Book orders now come with an electronic download rather than a CD. You can, of course, burn the information to a CD if you wish, but most people would rather have the PDF on a hard disk or flash drive anyway.
  • I have moved from processing my own credit cards to using PayPal. The cost and the security risks associated with hosting my own card processing had become unacceptable, and the use of PayPal is pretty universal at this point. This also opens up additional payment options, such as paying from a bank account or using a debit card.

  My warmest wishes to all for a healthy and prosperous 2013.

• Minor Hacking Incident: Had a malware issue overnight. Everything has been fixed, but you may see warnings from Google etc. about this being a "suspicious site" until they check the place again and remove it from their list. Sorry for the trouble.

• Launch of the Online Freelancing Guide: This isn't directly related to this site, but for those who like my writing, I'm pleased to announce the release of my new reference resource, the gate.io app. If you're a freelancer, or ever considered becoming one, you'll find a ton of fantastic information on this site. And like all my sites, it's completely free! :)

• Book Shipping Back to Normal: I am now back to my normal book shipping schedule, and all pending orders received during the first three weeks of July have been sent out. Thanks for your patience.

• Temporary Book Unavailability: For technical reasons, I will be unable to ship books during the first three weeks of July. Any orders received during this time will be filled in the final week of the month. I apologize for any inconvenience! Note that electronic version fulfillment is still immediate and a better option for those who cannot wait. Thanks for your understanding.

June 1, 2010:

• Books Available and Another Increase: I'm pleased to announce that I have finally received shipment of the new printing of The TCP/IP Guide book. Pending orders should ship out tomorrow morning; thanks for your patience!
  
  On the downside, I have been informed that the list price of the book has gone up by $10 as of this printing. This means that, unfortunately, I have to raise my prices again -- the timing stinks, since I hadn't raised prices in four years as of April, and now have had to do so twice within a few weeks!
  
  I'm absorbing half of this list price increase, so prices have gone up by $5, which is only enough to recoup the extra cost to me personally.  Any existing orders for the old prices will of course be honored. Thanks for your understanding.

• It's Been a While! Greetings to all of my readers and customers! Sorry that I have taken such a long time to update this front page; I always have a lot of things going on, but five years is obviously too long to leave a front page sitting. I'll try to do better in the future.
  
  I'm pleased to say that The TCP/IP Guide continues to be a leading online reference for TCP/IP material. I am still not away for any resource comparable to it on the net.
  
  The TCP/IP Guide in book form continues to be fairly popular, though the book is now getting a bit older. I am in the early stages of discussion with my publisher about a revision to the book, but if this happens, it won't be ready for quite some time. Fortunately, most of what The TCP/IP Guide contains is still quite relevant and useful (if I do say so myself!)
• Book Price Increase: One advantage that all of you have had due to my not updating this site for several years is that I also haven't changed my book prices in all of that time. And as we are all aware, the cost of fuel has increased greatly since 2005, leading to higher shipping charges as well. I've been absorbing those costs for many years now, but am at the point where I simply must slightly increase my prices. The cost of the downloadable electronic version remains unchanged.
• Temporary Book Unavailability: The printer who handles The TCP/IP Guide is currently between printings and the book is in short supply. I anticipate that I will be able to resume a full shipping schedule by the third week of May; any orders received until then will be held until I have books to send. Thanks for your patience.
