I would concur. worm is not attacking multicasting in general, but seems to be generating multicast traffic.
For these two statements to make sense, the IP address scanning must be very non random. This does not appear

all of our Internet links saturated outbound but we didn't appear to see any
noticable increase in our Internet2 bandwidth. I'm throwing this out there
because it may indicate that the destinations for the traffic - though large -
aren't completely random.

Has anyone else seen this?
