پرو DNS و BIND

The Domain Name System (DNS) is the system created to map domainnames to IP addresses, and is largely responsible for the widespreadpopularity of the Internet due to the convenience it offers incalling system resources by an easily recognizable name rather than acryptic number. Given the critical nature of this technology forensuring smooth operation of Internet-based resources such as Web andmail servers, it's imperative that users fully understand keyconfiguration, management and security principles. Pro DNS and BINDguides readers through the often challenging array of featuressurrounding DNS with a special focus on the World's most diffuseDNS implementation, BIND (Berkeley Internet Name Domain). Readerswill learn not only about key DNS concepts, but also how toeffectively install, configure, deploy and manage BIND in enterpriseenvironments.

Pro DNS and BIND guides you through the challenging array of features surrounding DNS, with a special focus on BIND, the world’s 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 9.3.0 the 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.
