Finding all subdomains that point to an IP?
Hi there,
Some clients pointed subdomains of different websites to the IP of a server whose IP address is going to change.
How can we find all the domain entries that point to a given IP? Most do not have reverse DNS entries.
Is it possible at all? Thanks.

Why?
The Server IP has nothing to do with the Client Domains, sub-domain or otherwise. It is the Nameservers they are using that counts. Once the Reseller updates their Nameserver with their new IPs all their Client Domains will automatically redirect to point to them.• PotentProducts.com - for all your Hosting needs

By conventional means (dig) no.
While this by no means is fool proof, if they have been around a while, you might find some useful information using http://www.whois.sc
By entering the IP in question, it should list many of the various domains that are hosted on that IP.

I think you have to clarify the question. How are these "different" websites different, and how did the clients point their domains at your server?
Are you saying that the clients are using their own separate nameservers?TWSites.com - Business Web Hosting Solutions & Server Management Since 2003

Yes, they use separate nameservers.
