Thanks for the links. I guess I need to sit down and focus on that for a few weeks.

It's a long story, but in short: I grew up watching Star Trek: TNG, and it shaped my interests quite profoundly.
DNS is really just a fancy address book. My point above was really aimed at AD sysadmins - if you have AD then you will also have MS DNS which is very easy to setup compared to say BIND or PowerDNS (my weapons of choice).
It's a bit hard for me to give recommendations but you could poke around here: http://www.bind9.net/manuals and here: https://www.powerdns.com/documentation.html and the WP page for DNS is probably quite complete.
