Most networking professionals will never have to write custom TCP/IP code, but they will have to understand the key issues associated with planning, operating, evolving, and troubleshooting IP networks. Gilbert Held's TCP/IP Professional Reference focuses on precisely these issues.
Held, who's authored dozens of networking books over the years, maintains a reputation for clarity (witness the online reviews of his recent work, such as Voice and Data Internetworking). In this book, he presents concise, useful introductions to the entire TCP/IP protocol suite and each component protocol, including ICMP, TCP, UDP, and others.
Held identifies the key issues associated with network addressing, subnetting, and routing; then introduces key TCP/IP applications such as DNS, and diagnostic tools such as ping, traceroute, NSLOOKUP, and finger. There's also to-the-point coverage of securing TCP/IP hosts via access lists and firewalls.
You'll also find thoughtful introductions to emerging TCP/IP technologies, from the relatively familiar VoIP and VPN to others, such as Mobile IP and IPv6, which haven't fully left the nest. TCP/IP Professional Reference is designed to be both an authoritative reference and a tool for day-to-day network decision-making. It does the jobs.(Bill Camarda)
