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

The DNS & BIND Cookbook presents solutions to the many problems faced by network administrators responsible for a name server. Following O'Reilly's popular problem-and-solution cookbook format, this title is an indispensable companion to DNS & BIND, 4th Edition, the definitive guide to the critical task of name server administration. The cookbook contains dozens of code recipes showing solutions to everyday problems, ranging from simple questions, like, "How do I get BIND?" to more advanced topics like providing name service for IPv6 addresses. It's full of BIND configuration files that you can adapt to your sites requirements. With the wide range of recipes in this book, you'll be able to * Check whether a name is registered * Register your domain name and name servers * Create zone files for your domains * Protect your name server from abuse * Set up back-up mail servers and virtual email addresses * Delegate subdomains and check delegation * Use incremental transfer * Secure zone transfers * Restrict which queries a server will answer * Upgrade to BIND 9 from earlier version * Perform logging and troubleshooting * Use IPv6 and much more. These recipes encompass all the day-to-day tasks you're faced with when managing a name server, and many other tasks you'll face as your site grows. Written by Cricket Liu, a noted authority on DNS, and the author of the bestselling DNS & BIND and DNS on Windows 2000, the DNS & BIND Cookbook belongs in every system or network administrator's library.

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

Until recently, learning CoreDNS required reading the code or combing through the skimpy documentation on the website. No longer. With this practical book, developers and operators working with Docker or Linux containers will learn how to use this standard DNS server with Kubernetes. John Belamaric, senior staff software engineer at Google, and Cricket Liu, chief DNS architect at Infoblox, show you how to configure CoreDNS using real-world configuration examples to achieve specific purposes. You’ll learn the basics of DNS, including how it functions as a location broker in container environments and how it ties into Kubernetes. Dive into DNS theory: the DNS namespace, domain names, domains, and zones Learn how to configure your CoreDNS server Manage and serve basic and advanced zone data with CoreDNS Configure CoreDNS service discovery with etcd and Kubernetes Learn one of the most common use cases for CoreDNS: the integration with Kubernetes Manipulate queries and responses as they flow through the plug-in chain Monitor and troubleshoot the availability and performance of your DNS service Build custom versions of CoreDNS and write your own plug-ins
