About this product: The Domain Naming System (DNS) is a glorious thing. It takes familiar Internet network and machine names (like "amazon.com") and converts them to Internet Protocol (IP) addresses (like "208.35.218.15") that are meaningful to routers and therefore useful for identifying the machine you want to reach. What's amazing is that DNS enables someone in Germany to refer, by name, to a computer in Mongolia even if no one in Germany has ever accessed the distant machine before. It's pretty much self-configuring, too: No human effort in Germany is necessary to make the Mongolian machine reachable by name. DNS and BIND explains how DNS works better for this than any other piece of documentation, printed or otherwise. The work of Paul Albitz and Cricket Liu, now in its fourth revision, has long been considered a classic among systems administrators and network architects, particularly those with a Unix bent.
The fourth edition is mainly an update: The authors have added coverage of incremental and conditional zone transfer with BIND's new NOTIFY features, as well as of Transaction Signatures (TSIG), and DNS Security Extensions (DNSSEC). Sections on firewalling and DNS for IPv6 addresses have been expanded. Throughout, Albitz and Liu maintain their impeccable style, combining text and illustrative listings into an educational whole. --David Wall
Topics covered: The Domain Naming System (DNS) and how it's implemented by BIND (through versions 8.2.3 and 9.1.0), how to set up BIND, how to configure MX records for mail service, parent and child domains, NOTIFY, and DNS security.
About this product: * Unique entry-level guide to Domain Name System (DNS), which translates Internet host names into IP addresses and is used with all Internet servers * Shows how to install, configure, and troubleshoot DNS on both Windows and UNIX servers * Helps people seeking technology certifications bone up on DNS theory, terminology, and architecture-a requirement in several popular exams * Includes real-world examples based on the author's daily experience with both large and small networks
About this product: 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 issues
System tuning
Caching
Zone change notification
Troubleshooting
Planning for growth
If 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.

Pro DNS and BIND guides you through the challenging array of features surrounding DNS, with a special focus on BIND, the worlds most popular DNS implementation. This book unravels the mysteries of DNS, offering insight into origins, evolution, and key concepts like domain names and zone files. This book focuses on running DNS systems based on BIND 9.3.0the first stable release that includes support for the latest DNSSEC (DNSSEC.bis) standards and a major functional upgrade from previous BIND 9 releases.
If you administer a DNS system or are thinking about running one, or if you need to upgrade to support IPv6 DNS, need to secure a DNS for zone transfer, dynamic update, or other reasons, or if you need to implement DNSSEC, or simply want to understand the DNS system, then this book provides you with a single point of reference. Pro DNS and BIND starts with simple concepts, then moves on to full security-aware DNSSEC configurations. Various features, parameters, and resource records are described and, in the majority of cases, illustrated with one or more examples.
The book contains a complete reference to zone files, Resource Records, and BINDs configuration file parameters. You can treat the book as as a simple paint-by-numbers guide to everything from a simple caching DNS, to the most complex secure DNS (DNSSEC) implementation. Background information is still included for when you need to know what to do and why you have to do it, and so that you can modify processes to meet your unique needs.
Topics Include:
Introduction to the DNS Basic DNS types with complete configuarion examples DNS and IPv6 Installing BIND on Linux, FreeBSD and Windows Subdomain delegation DNS and load balancing Reverse map delegation DNSSEC (DNSSEC.bis) and the DLV experimental service Key rollover and DNSSEC maintenance DNS tools and diagnostics
Providing a complete survey of DNS (Domain Name System) servers, this reference outlines the most suitable types of servers for varying scenarios. Addressing performance and security issues, this resource describes in detail the ideal scenarios for each server. Additional topics discussed include how DNS information can be stored in LDAP (Lightweight Directory Access Protocol) directories or SQL databases as well as how to construct robust DNS systems.
About this product: The Domain Name System is one of the foundations of the internet. It is the system that allows the translation of human-readable domain names into machines-readable IP addresses and the reverse translation of IP addresses into domain names. This book describes the basic DNS protocol and its extensions; DNS delegation and registration, including for reverse domains; using DNS servers in networks that are not connected to the internet; and using DNS servers on firewall machines. Many detailed examples are used throughout the book to show perform various configuration and administration tasks.
Chapter 1 introduces basic DNS concepts, such as domains and subdomains, domain naming syntax, reverse domains, zones, queries, resolvers, name servers, forwarder servers. Chapter 2 explains the DNS protocol, focusing on DNS query. The chapter makes use of several examples of DNS client-server communication. Including an example of a non-existent RR query and its answer, communication with a root server, and TCP and UDP DNS queries. Chapter 3 describes extension to the DNS protocol, including DNS Update, DNS Notify, Incremental Zone Transfer, Negative caching, DNS IPv6 Extension, DNSsec, and TSIG. Chapter 4 discusses name server implementations, focusing on Bind, versions 4, 8, and 9. The use and configuration of the program named is explained in detail. The chapter also discusses the Windows 2000 implementation. Chapter 5 covers DNS tuning and administration and tools, such as named-checkconf, named-checkzone, nslookup, dnswalk, dig, and rndc. Chapter 6 focuses on DNS delegation from a primary to secondary servers. The process of domain registration is also explained in the chapter. Chapter 7 talks about the delegation and registration of reverse domains. The internet registry is the subject of Chapter 8. It covers the regional internet registry, division of the world between RIR and country codes, and RIPE database and its various objects. Chapter 9 shows how to configure DNS servers in closed intranets, i.e. networks that are not connected to the internet. It covers configuring a root name server on a separate server (BIND 4) and configuring a name server for the root domain. Chapter 10 covers sharing a DNS database between the Internet and intranet, as well as having separate servers. It also discusses installing name servers on firewalls.
About this product: Linux, which is well suited to fire-and-forget applications that require high reliability, can make an excellent foundation on which to build a Domain Name System (DNS) server. Linux DNS Server Administration shows how to do that, treating Linux generically (the book sticks to features of the 2.x kernel that are common to all distributions) and showing how to configure Berkeley Internet Name Domain (BIND) on top of that base. The result is a technical document that's focused, detailed, and oriented toward the practical considerations--such as security--of real-world system administration.
Because providing DNS service isn't as much a matter of administration as of proper initial setup, Linux DNS Server Administration spends about half the time describing what a DNS server does and explaining how to get BIND service going. It mainly steers clear of "do-this, do-that" instructions, favoring statements of problems and their solutions (with lots of configuration file listings), instead. A similar approach later shows how to plug known security holes, configure logging, and optimize performance. For more information on DNS and BIND, check out the classic DNS and BIND. Although it's not focused specifically on Linux, that's the definitive work on name resolution under Unix generically. --David Wall
Topics covered: Domain Name System (DNS) service under Linux 2.x, as provided by BIND 8. The design of the global DNS service, server configuration (for both master and slave servers), subdomains, security, and performance optimization. DNS futures--in the form of a look at BIND 9--appear, too.
The Concise Guide to DNS and BIND provides you with the technical depth and expert-level information you need 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. This book covers 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, new features in BIND 8.2.2, and it offers introductory information on BIND 9.
About this product: The BIND 9 DNS Administration Reference Book is a convenient resource covering the tools and configurations for the ISC BIND 9 DNS software suite. BIND (Berkeley Internet Name Domain) is the most commonly-used DNS server on the Internet. BIND provides the named DNS server, a resolver library, and various tools for operating and verifying the DNS server and configurations. The BIND 9 implementation includes DNSSEC for signed zones, TSIG for signed DNS requests, IPv6 support, incremental zone transfers (IXFR), dynamic DNS, zone change notifications, EDNS0, multiple views, multi- processor support, and more. This printed book is based on a variety of open source documentation included with the BIND source code, including the definitive references for the configuration syntax and grammar and the usage of the BIND programs. New chapters and content were added, including many examples and detailed indexing and cross-referencing. This BIND 9 DNS Administration Reference Book corresponds to BIND 9.5 and also covers some differences between older versions.
