I first started reading vol.1, but it was not what a programmer expected. So I started reading vol.2 and, wow, that was it. It was my start point to kernel level network programming under freeBSD. With the informations, you can get out of this book, you can do everything. You can implement your own protocols, or just have fun hacking around your kernel code.
The line by line comments are very very useful, especialy for programmers, not yet familar with kernel level programming.

If you want to know the internal mechanisms used to build an IP stack, and how the mechanisms are implemented, this is the book to refer to. The level of detail is very impressive. Although Vol.1 can be read as a text book, Vol.2 is really a reference book with a large quantity of code. It is very easy to read and well indexed (very important for a book of this nature). Simply put, it's one of the best TCP/IP implementation books I've encountered yet.

This book requires a strong knowledge of TCP/IP in order to get the most from it. Once you have that, I recommend that you read this book in order to get a firm understanding of how TCP/IP actually WORKS. Be advised, though...this text is a borderline reference book. Stevens (as you probably know) has a dry writing style, so be sure to fill up on your favorite caffinated drink before digging in ;)
