The TCP/IP Guide is a reference resource on the TCP/IP
protocol suite that was designed to be not only comprehensive, but
comprehensible. Organized using a logical, hierarchical structure, The
TCP/IP Guide uses a personal, easy-going writing style that lets anyone
understand the technologies that run the Internet. The Guide explains dozens of protocols
and technologies in over 1,500 pages. It includes full coverage of PPP, ARP,
IP, IPv6, IP NAT, IPSec, Mobile IP, ICMP, RIP, BGP, TCP, UDP, DNS, DHCP,
SNMP, FTP, SMTP, NNTP, HTTP, Telnet and much more.
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!

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
- 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!)

- 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
Online Freelancing Guide. 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

- 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
- 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

- 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
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
- 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.
