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
to be the sort of consecutive address block scanning that the RAMEN worm 
did.

(BTW, This AM we have 11052 I2 routes vs 116983 in all, or about 9.4% of 
the total.)
