Internetworking with TCP/IP Vol.1: Principles, Protocols, and Architecture (4th Edition)

I knew nothing about TCP/IP. As a result, I bought a book "learn TCP/IP in 24 hours" and trashed it after I bought this book, no more 24 hour books. I had no idea what routing is and were to start looking for documents on the internet. This book is scientific and puts it all together. Each chapter lists the RFC that he relied on so you know were the stuff came from. The book is not boring; the author is excellent in explaining ideas. He covers ICMP, GGP, OSPF, EGP, DHCP, DNS, BOOTP, ARP and more. I feel I have accomplished something big by reeading this book. If you are not a beginner in routing, then look at the RFCs they are the source.

I love it when I can get good resources for pennies, literally. The book was in great condition and I only paid .01 for it. I had to pay more for the shipping and handling.

Many networking books I read (or other books on similarly technical subjects) have a tendency to get bogged down in technical minutia that distracts from the big picture. Not so here. Cormer does an excellent job of getting all the important information out there and explains the common networking protocols, what goes into them, and what they do, without losing the reader. Do not think that this is a superficial view though - I've been in the field for several years now and still use it as a reference on occasion.

I am grateful for this book. I like to really understand things and this book makes understanding a reality. It is an exemplary model of technical writing. This is the fourth book I have read on TCP/IP and it should have been the first. Since I am a network engineer with no background in programming some of the illustrations from BSD Unix sailed over my head but there was not enough of this to make me feel that any of my time was wasted. In fact, now I want to get a solid introduction to programming so that I can follow along with the rest of the series this book begins.

Douglas Comer is the definitive work on TCP. A book every developer should read.

I have been doing Internet protocol engineering for 12 years and I can say that people in the industry consider Comer Vol 1 to be the bible for Internetworking reference. The fourth edition is nearly three times as thick as my copy of the first edition. Douglas Comer keeps this book up to date and useful for modern Internet developers. If you're a student, read this book. I've gone through a lot of books that claim to be the same thing as Comer Vol 1 and have found none that really compare.

The book has some writing in it, but is in "like-new" condition otherwise. I'm VERY happy for what I paid for this book. Thank you so much!

i love this book it is rich of information for people who want to do any IT certification. i used it and now i have my CCNA, CCNP CCDA CCNA sec,
