As the title suggests, TCP/IP Blueprints details the TCP/IP protocols, including the basic protocols as well as various common applications. The text contains an excellent discussion and comparison of the differences between the new and old versions of the Internet Protocol (IP). TCP/IP Blueprints also covers network management issues quite well, particularly security configuration and some useful information in the troubleshooting section. As an added bonus, the book's appendix contains an index that maps an application and/or a protocol to the appropriate RFC (Request for Comments) document. This index-mapping feature makes it easy to get standards information so you can find "the last word" on the subject.
