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,
