If you're preparing to roll out IPv6 on your network, this concise book provides the essentials you need to support this protocol with DNS. You'll learn how DNS was extended to accommodate IPv6 addresses, and how you can configure a BIND name server to run on the network. This book also features methods for troubleshooting problems with IPv6 forward- and reverse-mapping, and techniques for helping islands of IPv6 clients communicate with IPv4 resources. Topics include: *DNS and IPv6-Learn the structure and representation of IPv6 addresses, and the syntaxes of AAAA and PTR records in the ip6.arpa IPv6 reverse-mapping zone *BIND on IPv6-Use IPv6 addresses and networks in ACLs, and register and delegate to IPv6-speaking name servers *Resolver Configuration-Configure popular stub resolvers (Linux/Unix, MacOS X, and Windows) to query IPv6-speaking name servers *DNS64-Learn about the transition technology that allows clients with IPv6-only network stacks to communicate with IPv4 servers *Troubleshooting-Use the nslookup and dig troubleshooting tools to look up the IPv6 addresses of a domain name, or reverse-map an IPv6 address to a domain name

DNS and BIND tells you everything you need to work with one of the Internet's fundamental building blocks: the distributed host information database that's responsible for translating names into addresses, routing mail to its proper destination, and even listing phone numbers with the new ENUM standard. This book brings you up-to-date with the latest changes in this crucial service. The fifth edition covers BIND 9.3.2, the most recent release of the BIND 9 series, as well as BIND 8.4.7. BIND 9.3.2 contains further improvements in security and IPv6 support, and important new features such as internationalized domain names, ENUM (electronic numbering), and SPF (the Sender Policy Framework). Whether you're an administrator involved with DNS on a daily basis or a user who wants to be more informed about the Internet and how it works, you'll find that this book is essential reading. Topics include: * What DNS does, how it works, and when you need to use it * How to find your own place in the Internet's namespace * Setting up name servers * Using MX records to route mail * Configuring hosts to use DNS name servers * Subdividing domains (parenting) * Securing your name server: restricting who can query your server, preventing unauthorized zone transfers, avoiding bogus servers, etc. * The DNS Security Extensions (DNSSEC) and Transaction Signatures (TSIG) * Mapping one name to several servers for load sharing * Dynamic updates, asynchronous notification of change to a zone, and incremental zone transfers * Troubleshooting: using nslookup and dig, reading debugging output, common problems * DNS programming using the resolver library and Perl's Net::DNS module
