This module will walk you through the configuration of a DNS name server. In the Linux world, DNS is generally maintained by the BIND software, which is currently in it's 9th revision. There are, of course other DNS server software out there, but since almost the entire Internet uses BIND, and it has been the most long-serving DNS server, we will focus on BIND in this course.[2]
Before we being diving into configuring BIND, we need to review a couple of topics that you may or may not know about. We will also need to sketch the setup of our private network to make understanding the structure of our DNS simpler.
[2] The other DNS server that is becoming popular is Dan Bernstein's djbdns DNS server. See http://djbdns.org for more information on this DNS server alternative.
