Try one of the following from your favorite *nix variant:
$ dig @{server you want to query} -x {ip address} +short +norecurse
or
$ host -r {ip address} {server you want to query}
Windows nslookup is kind of pathetic but I believe you can do the same
with it as follows:
C:\> nslookup -norecurse {ip address} {server you want to query}
--
