Managing Mission - Critical Domains and DNS

By: Mark E.Jeftovic

Overview of this book

Managing your organization's naming architecture and mitigating risks within complex naming environments is very important. This book will go beyond looking at “how to run a name server” or “how to DNSSEC sign a domain”, Managing Mission Critical Domains & DNS looks across the entire spectrum of naming; from external factors that exert influence on your domains to all the internal factors to consider when operating your DNS. The readers are taken on a comprehensive guided tour through the world of naming: from understanding the role of registrars and how they interact with registries, to what exactly is it that ICANN does anyway? Once the prerequisite knowledge of the domain name ecosystem is acquired, the readers are taken through all aspects of DNS operations. Whether your organization operates its own nameservers or utilizes an outsourced vendor, or both, we examine the complex web of interlocking factors that must be taken into account but are too frequently overlooked. By the end of this book, our readers will have an end to end to understanding of all the aspects covered in DNS name servers.

Types and Uses of Common Resource Records

PowerDNS

PowerDNS is an authoritative nameserver (distinct from the PowerDNS Recursor) that can be described as a core nameserver engine that utilizes one or more backends. Those backends support a myriad of database platforms and different nameserver emulators.

For example, there is a BIND backend to PowerDNS, which lets you run your server with native BIND-style zonefiles.

You can specify multiple backends and a query will be attempted in each backend, in order, until a match is found.

Finally, the end user can code their own custom backends for PowerDNS, making it one of the most versatile of the prime-time-ready nameservers we've ever worked with.
