All the threads I've read on Reverse-DNS here discuss Enabling Reverse-DNS. I'm trying to find a solution for the exact OPPOSITE problem... I want to limit rDNS queries so they report only the server hostname (and not all hosted domains).

Using Reverse DNS queries, anyone can get all the domains hosted on the server IP. For ex. http://www.seologs.com/ip-domains.html lists 144 domains hosted on my server IP... the actual hosted domains are over 300, but this tool just lists 144. I'm trying to setup rDNS so it reports only 1 domain and not all hosted domains.

I've already setup a zone with the 4.3.2.1.in-addr.arpa syntax and created the corresponding PTR record using my server hostname. Will this fix the issue or something more needs to be done?
 
Here's a hard-hitting example of what I don't want...

Do a search for this IP: 207.46.197.32


This is the IP for microsoft.com and it lists 104 hosted domains (interesting list of domains if you read carefully)

I consider this very awkard since I'm currently in SE marketing and this damn query is listing all my own and client websites to the public.
 
You're doing reverse DNS wrong. You shouldn't set up reverse DNS for one IP# for more than one domain.

You don't give us enough information to know if you control your own reverse DNS or if your upstream does it for you. Presuming you do it yourself find the entry for the reverse zone in your DNS zone list, and edit it to what you want. And in the future when you create a DNS zone don't automatically include reverse DNS.
