| 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 guide to the Domain Name System, its implementation, configuration, & administration covers the basics as well as the more advanced features & uses of DNS. It describes the basic DNS protocol and its extensions; DNS delegation & 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 examples show configuration & administration tasks.
This book is for system administrators & network architects who need to learn how to run & configure DNS servers. A working knowledge of TCP/IP protocols is presumed.
