Thanks for the ID - that makes sense given the hostnames. I guess we have
another braindead vendor to add to our hall of shame. Have these people never
heard of:

- IANA?
- admin scoped groups?

Hmm, and they seem to join the group as well. So anyone with one of these
pieces of junk probably ought to either disable multicast on the subnet where
they're located, or filter that group at the edge.

Bill.
