i only have one static IP address. the ispconfig 3 hosting server is using this IP address. i registered 2 domains, hostingdomain.com and websitedomain.com. server1.hostingdomain.com is the hostname for this hosting server. the primary nameserver is ns1.hostingdomain.com and the secondary nameserver is provided by the registrar. this is the setup of my hosting environment and the registered domains.

i want to host multiple drupal sites in this server. the hostingdomain.com is for the drupal core and the websitedomain.com is for the 2nd drupal site shared the drupal core of hostingdomain.com.

is it able to achieve the above with ispconfig 3? how? it is much appreciated if you can provide some detailed information on this.
