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. The Concise Guide to DNS and BIND provides readers with technical depth and the expert-level information they need to understand and administer DNS and BIND. Covered topics include the following: Setting up a DNS server and client, DNS domain zones, Compiling and configuring BIND, Dial-up connections, Adding more domains, Setting up root servers on private networks, Firewall rules, Dynamic DNS (DDNS), Subdomains and delegation, Caching and name resolution, Troubleshooting tools and techniques, Debugging and logging, and New features in BIND 8.2.2.
