HOW TO: Run Your Own Name Servers With ISPConfig And GoDaddy
This tutorial shows how you can run your own name servers for domains that you register with 
GoDaddy. Of course, this works with every other registrar as well, although the procedure might differ a little bit.
To do this, you need two servers with two different public IP addresses and with ISPConfig installed, and of course a GoDaddy account.
1. Current Situation
Our current situation is as follows: we have
* ISPConfig server #1: IP address 64.25.171.8; this one will be our primary name server.
* ISPConfig server #2: IP address 64.25.171.9; this one will be our secondary name server.
* a GoDaddy account with the already registered domains erikturk.com and ifwolfpack.com. Both are currently using GoDaddy’s name servers (e.g. park27.secureserver.net and park28.secureserver.net). How To Run Your Own Name Servers With ISPConfig And GoDaddy | HowtoForge - Linux Howtos and Tutorials
