I think Frank mentioned the packets being like 2048 in size, and this
makes me wonder if it's a tad more then mere recon.  Might be trying to
exploit or develope an exploit for bind.  and might be a tool in progress
for a specific bind OS combo.

But, I find just tossing the offenders into the "not allowed" list of
entowrk addresses reduces the log fluff as well as hinder progressive
testing, for them, at least off my networks.

Thanks,
