The author breaks TCP/IP into several logical units--general concepts, IP addressing (including routing, subnets, and Dynamic Host Configuration Protocol [DHCP]), name resolution (including Windows Internet Naming Service [WINS], Domain Name System [DNS], and NetBIOS) and advanced topics (mainly protocol bridging, Simple Network Management Protocol [SNMP], and troubleshooting). Each topic is covered with plenty of clear, explanatory prose, some concise tables (typically showing parameters), and a number of excellent conceptual diagrams. Step-by-step procedures appear where they are needed, but aren't so numerous as to become overbearing. One would like to see more about integrating NT-based TCP/IP with a legacy Novell NetWare LAN.
