I wanted to know how this normally works, I'm very new to websites and hosting, and I have to get one going for our site. We already have a webmail server going for our users.
For example we have a site linking to our SBS 2011 at ex. webmail.com
We are also installing an application server. ex. application.com
Let's say they only have one external address of 18.104.22.168
For example we have a Godaddy account that host both of the external DNS names, and both points to 22.214.171.124..
Can we still use just one external IP addresses? I called the ISP and apparently we have 4 external IP addresses allocated for us. Is there a point for that? I see a couple of them are dedicated for VPN's.
