Well, if you have to ask..... :)) Running public servers on private ip's (or whatever they are doing) is always much trickier than running them on public ip's. "port (address) mapping" is often coupled with "network address mapping" or translation, or as Cisco calls it, PAT/NAT. So, I'm guessing, you will have one public ip (which is what they gave you to register as glue record for your registered DNS host), and the router they will put your site will PAT/NAT from the public ip on the "outside" of the router to a private ip on the "inside" of the router. It could work, but it's pretty fidgety, esp when it comes to reverse zone, plus your inside machines using the inside DNS for public lookups and private lookups.
