I appologize if this is a FAQ, but I can't find such a thing right now.

Is this among issues with djdns? Or another? I will complain to the ISP
who has hired this service as soon as I have the right ammunition.

marajade-[~] root 86 #named -version 
BIND 9.3.0s20021115

running as a local recursive name server, I have a process doing TXT
lookups on my reverse IP (a dialup from uu.net) and my local named9 is logging:

I do the equivalent lookup:

Looking for version.bind. on that server gives me nothing, so I assume it is
not bind.

Some tcpdump:

I.e. I am getting a referral from a server that is supposed to be
authoritative. Note that it is authoritative for other record types!
