I am seeing these requests from 2 diffrent sources.  The first is a
packet filter on the CPE router.  They have a Livingston IRX 114 and I
am using ptrace to watch all udp packets going to the name server on
port 53.  The second is a packet sniffer on the ethernet, this is where
I am getting the domain requests from.
