Dear misters, I'm trying to learn how to use ISP Config, I always used the vps with WHM/CPANEL, and everything was always ready... Now I'm trying to learn ISPConfig together with DNS concepts. So I got a vps using openvmz, followed the tutorial on perfect server tutorial.. and begin to study about DNS and other linux server stuff.. While I begun read about DNS, would be good to have a second IP on the vps? Do the second Ip is required to the DNS server work within ISPCONFIG.. or I could use the DNS from the vps vendor to point to the multiple websites hosted on ISP Config. I always use the ready WHM/Cpanel contrated from web companies, so now I'm trying to understand a bit more, other than just using the system. thanks.
AFAIK you need for each Nameserver, of which you need at least 2, a separate public IP for each. If you use the Nameserver from your Registra, you need 1 public IP and use an A Record at Registra for to resolve to your Domain name. The button line is: for each nameserver 1 public IP min. 2 nameservers are need if you like to use your own nameserver That would looks like: 'ns1.yourdomain.com' for IP1 like 123.24.54.11 'ns2.yourdomain.com' for IP2 like 987.65.54.23 cPanel and WHM are quite expensive and hardly used by private hosting. cPanel as example sell licenses for a bunch of 500 domains! The free Enkompass cPanel is still available but the development has stopped and the Service of the Company is on forum only and not good anymore.
