Aye, put two and two together today talking to my upstream provider. 
I've been running tcpdump most of the day today and will check the logs 
tomorrow. My immediate upstream provider isn't blocking it, though. 
Monday (when they're back in), I'll look over the logs and see if/how 
often I am being queried from the 99.0.0.0/8 range.

Thanks kindly for the info! With luck this may be the issue.
