I'm working on an Internet Draft that describes current practice for IPv4 
Multicast routing.  This Internet Draft includes a table of IPv4 multicast 
groups that I've sort of picked up over time that are generally 
black-holed.  Following is the table that I have; do you use the same table 
of known-bad groups?  Are there any other groups that you believe should be 
included in this table?

224.0.1.2/32:      SGI "Dogfight" game
224.0.1.3/32:      RWHOD
224.0.1.22/32:     SVRLOC
224.0.1.24/32:     MICROSOFT-DS
224.0.1.35/32:     SVRLOC-DA
224.0.1.39/32:     Cisco's Rendezvous Point Announcement Protocol
224.0.1.40/32:     Cisco's Rendezvous Point Discovery Protocol
224.0.1.60/32:     HP's Device Discovery Protocol
224.0.2.2/32:      Sun's Remote Procedure Call Protocol
229.55.150.208/32: Norton "Ghost" disk duplication software


Please send me direct email and I'll summarize the results back to these 
lists (wg-multicast, nanog, and mboned).

Thank you,
