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. Youll 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 zonesLearn how to configure your CoreDNS serverManage and serve basic and advanced zone data with CoreDNSConfigure CoreDNS service discovery with etcd and KubernetesLearn one of the most common use cases for CoreDNS: the integration with KubernetesManipulate queries and responses as they flow through the plug-in chainMonitor and troubleshoot the availability and performance of your DNS serviceBuild custom versions of CoreDNS and write your own plug-ins

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 IPv6Learn the structure and representation of IPv6 addresses, and the syntaxes of AAAA and PTR records in the ip6.arpa IPv6 reverse-mapping zoneBIND on IPv6Use IPv6 addresses and networks in ACLs, and register and delegate to IPv6-speaking name serversResolver ConfigurationConfigure popular stub resolvers (Linux/Unix, MacOS X, and Windows) to query IPv6-speaking name serversDNS64Learn about the transition technology that allows clients with IPv6-only network stacks to communicate with IPv4 serversTroubleshootingUse 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, "e;How do I get BIND?"e; 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 toCheck whether a name is registeredRegister your domain name and name serversCreate zone files for your domainsProtect your name server from abuseSet up back-up mail servers and virtual email addressesDelegate subdomains and check delegationUse incremental transferSecure zone transfersRestrict which queries a server will answerUpgrade to BIND 9 from earlier versionPerform logging and troubleshootingUse IPv6and 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.

While computers and other devices identify each other on networks or the Internet by using unique addresses made up of numbers, humans rely on the Domain Name System (DNS), the distributed database that allows us to identify machines by name. DNS does the work of translating domain names into numerical IP addresses, routing mail to its proper destination, and many other services, so that users require little or no knowledge of the system. If you're a network or system administrator, however, configuring, implementing, and maintaining DNS zones can be a formidable challenge. And now, with Windows Server 2003, an understanding of the workings of DNS is even more critical.DNS on Windows Server 20003 is a special Windows-oriented edition of the classic DNS and BIND, updated to document the many changes to DNS, large and small, found in Windows Server 2003. Veteran O'Reilly authors, Cricket Liu, Matt Larson, and Robbie Allen explain the whole system in terms of the new Windows Server 2003, from starting and stopping a DNS service to establishing an organization's namespace in the global hierarchy. Besides covering general issues like installing, setting up, and maintaining the server, DNS on Windows Server 2003 tackles the many issues specific to the new Windows environment, including the use of the dnscmd program to manage the Microsoft DNS Server from the command line and development using the WMI DNS provider to manage the name server programmatically. The book also documents new features of the Microsoft DNS Server in Windows Server 2003, including conditional forwarding and zone storage in Active Directory (AD) application partitions.DNS on Windows Server 2003 provides grounding in:Security issuesSystem tuningCachingZone change notificationTroubleshootingPlanning for growthIf you're a Windows administrator, DNS on Windows Server 2003 is the operations manual you need for working with DNS every day. If you're a Windows user who simply wants to take the mystery out of the Internet, this book is a readable introduction to the Internet's architecture and inner workings.

Talks about 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 covers BIND 9.3.2 as well as BIND 8.4.7.
