Dump your nameserver's cache (ndc dumpdb) and look for A records pointing
to that address and NS records pointing to those names.

This may not find them, since it's possible that the errant records are in
some other site's cache but not yours.  In that case, what you'll need to
do is contact the administrators of the DNS servers that are sending those
queries and ask *them* to dump their caches.
