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.

What this book covers

Chapter 1, The Domain Name Ecosystem, describes what parts of the naming system affect specific functions of your domains.

Chapter 2, Registries, Registrars and Whois, outlines the relationship between registrants and registries, and the database that houses your registrant data.

Chapter 3, Intellectual Property Issues, examines issues like which domains your organization should register and how IP-based domain disputes work.

Chapter 4, Communication Breakdowns, lists the various ways in which a key domain can go offline because of procedural and organizational mishaps, and also details common scams to be aware of.

Chapter 5, A Tale of Two Nameservers, looks at the difference between resolvers and authoritative nameservers and how they work together to answer DNS queries.

Chapter 6, DNS Queries in Action, looks at the anatomy of a DNS query and how queries actually get from a resolver to an authoritative nameserver and back to the client.

Chapter 7, Types and Uses of Common Resource Records, takes you through each DNS Resource Record (RR) type on an individual basis.

Chapter 8, Quasi-Record Types, goes through record types that don't actually exist within the DNS protocol but are frequently managed from within the DNS infrastructure.

Chapter 9, Common Nameserver Software, looks past the near ubiquitous BIND server and examines alternatives, such as PowerDNS, NSD, tinydns, and Knot DNS, with an eye toward nameserver diversity.

Chapter 10, Debugging Without Tears – DNS Diagnostic Tools, digs into debugging tools for DNS, both command-line and web-based.

Chapter 11, DNS Operations and Use Cases, delves into DNS use cases; we will cover all the things people often want their nameservers to do (even if it breaks protocol.)

Chapter 12, Nameserver Considerations, explains that as your portfolio of names under management grows, it becomes more difficult to change some of the deployment decisions made early on. With this in mind, we want to try to create a sensible approach from the outset.

Chapter 13, Securing Your Domains and DNS, covers securing your naming infrastructure, including DNSSEC.

Chapter 14, DNS and DDoS Attacks, looks at DDoS mitigation considerations.

Chapter 15, IPv6 Considerations, is a short but sweet chapter where we look at IPv6 considerations and how they relate to DNS.
