The Concise Guide to DNS and BIND provides the technical depth and expert-level information needed to understand and administer DNS and BIND. Domain Name System (DNS) is a distributed Internet directory service. It is used mainly to translate between domain names and IP addresses, and to control Internet email delivery. Most Internet services rely on DNS to work, and if DNS fails, Web sites cannot be located and email delivery stalls. BIND (Berkeley Internet Name Daemon) is an implementation of the Domain Name System (DNS) protocols. Some of the topics covered are setting up a DNS server and client, compiling and configuring BIND, and setting up root servers on private networks. The Concise Guide to DNS and BIND also features expert knowledge on firewall rules, Dynamic DNS (DDNS), debugging and logging, plus new features in BIND 8.2.2. The book also offers introductory information on BIND 9.
