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.

Summary

In this chapter, we learned about what is involved in managing the operational functions associated with use cases, that they are not DNS per se, but frequently managed from within the same scope as the DNS operations.

On their own, providing these functions for a single or small number of domains is not rocket science. Subtle issues begin to emerge when scaling into the higher orders of magnitude, such as migrating the IP address on a couple of hundred thousand URL forwarders, or relaying millions of email messages per day across thousands of domains.
