The Domain Name System (DNS) is the system created to map domain names to IP addresses, and is largely responsible for the widespread popularity of the Internet due to the convenience it offers in calling system resources by an easily recognizable name rather than a cryptic number. Given the critical nature of this technology for ensuring smooth operation of Internet-based resources such as Web and mail servers, it's imperative that users fully understand key configuration, management and security principles. Pro DNS and BIND guides readers through the often challenging array of features surrounding DNS with a special focus on the World's most diffuse DNS implementation, BIND (Berkeley Internet Name Domain). Readers will learn not only about key DNS concepts, but also how to effectively install, configure, deploy and manage BIND in enterprise environments.
