Hi, I m a simple question about DNS configuration. How do you configure to have all your VPS servers to use one Name Server. Let say I have 5 VPS servers w/ 5 Ispconfig on it. I have 5 domains and want to use under 5 VPS Servers. I have setup NS1.domain1.com and NS2.domain1.com on one VPS and use domain1.com to use NS1 and NS2.domain1.com. This part works fine. Here is the tough one. How do I setup domain2.com, domain3.com, domain4.com, domain5.com to use NS1 and NS2.domain1.com Name Servers so all other domains on each of its VPS to use only under one name server. Domain2.com NS1.domain1.com NS2.domain1.com Domain3.com NS1.domain1.com NS2.domain1.com etc... What are the steps? because I m selling VPS servers and want customer to use their domains to use my Name Server. PLease explain. Thanks much.
