This looks to be a very good book on TCP/IP from what I have read. I read two chapters that have been placed online and both are very good. This chapter is on IPv6. It is a very good introduction to IPv6. This chapter is an introduction to the fundamentals and operation of TCP. It's one of the better explanations I've read, and by that I mean one of the easiest to understand explanations I've read. Based on these two chapters I would highly recommend this book for those wanting to understand the basics of networking.
