This is one book I can't seem to put down at all. The first few chapters are your basic Network+/Basic Networking stuff, but the rest is pure gold. Everything from understanding every fragment on a packet, to network administration.

For those of you looking for a good online compliment to many of the TCP books out there, check out the RFC Sourcebook.
The protocols section breaks everything down very well.
