Domain Mapping

I've installed domain mapping and have a dedicated ip address for my domain. When I type the ip address it shows my website - all good there.

The way the server is set up is that I have 2 ip addresses that are specified as nameservers and the third ip address is my website. The name servers are and The site is It resides on a ServInt server.

My question is are there instructions anywhere on what to tell users of how to map their domain? Is it the A name that must be changed on their zone file or is there a way to use my name servers?? That would be idea, of course - is there a way to make that happen?

Thank you!
