There are services that track IP usage and correlate them to domains.

The tools allow you to find out (approximately) what A records point to

any given IP.
This one is relatively accurate:
http://www.myipneighbors.com/
I would not treat its output as gospel. It gives a decent indicator of

how many virtual hosts are pointed at any given IP and shows you who

they are. Note, this only tracks A records, not MX records and is easily

confused by CNAMEs.
There is no way to query for this, you would have to get a list of all

FQDN's in use on the Internet and continuously dig them to record their

IP.
I don't know of any service that does this and offers free automated

queries via some kind of text client, most insist that you use their web

interface. This makes them handy for manual look ups but useless in any

kind of automated tool.
