Overview of this book

The Domain Name System is one of the foundations of the internet. It is the system that allows the translation of human-readable domain names into machines-readable IP addresses and the reverse translation of IP addresses into domain names. This book describes the basic DNS protocol and its extensions; DNS delegation and registration, including for reverse domains; using DNS servers in networks that are not connected to the internet; and using DNS servers on firewall machines. Many detailed examples are used throughout the book to show perform various configuration and administration tasks.

Chapter 6. Domain Delegation and Registration

The process of delegating a domain is carried out in several steps:

1. Setting up a primary Domain Name Server
2. Configuring a secondary name server for the domain, or requesting the configuration of the name server from your Internet service provider
3. Requesting that the domain be delegated to a higher-level domain
4. If the domain is a second-level domain, registering the domain in an Internet registry domain database

Let us say that, somewhere in the world, there is a magical land that uses the top-level domain tld as its country code. This top-level domain is similar to com, info, cz, fj, ru, de, or other domains used in neighboring fairytale lands. The wise old TLD manager of this land controls the primary name server for the tld domain in this country called ns.manager-tld.tld. The secondary name servers for the tld domain are held by his good friends, the hostmasters of other TLDs that are equally accessible from any place on the globe...
