The best way to do this is to install a name server on one of your hosts
and add something like this to named.conf:

logging {
        channel query_logging { file "/tmp/query.log"; print-time yes; };
        category queries { query_logging; };
};

Then find which process is doing these queries.
I just checked and it's not a tcpd problem, when I connect to a wrapped
port then only queries I see are:

27-Sep-2002 17:33:59.352 XX+/127.0.0.1/9.0.0.10.in-addr.arpa/PTR/IN
27-Sep-2002 17:33:59.352 XX+/127.0.0.1/wonderland.sv.bofh.it/A/IN


Anyway, as other people already explained, IPv6 is here and is not
going away, so unless you can find a real bug you will have to live with
this.
