Hmmm...

This would
prevent one from actually attacking from a network participating in
this
BGP session.

That is from my email...It stops the attack from happening...It will not
stop the attack if it is ongoing...Was there some confusion in how I
stated that?

    This topic is continously covered (as you can tell) so I'm not
sure where to go from here.  I've been looking into starting a BGP speaker
that announces the top 4000 smurf amplifiers from my list and the top 2000
from netscan, which in turn can be pushed to null0 or discard.  This would
prevent one from actually attacking from a network participating in this
BGP session.  I've tested it and it's working on a couple smaller ISPs as
we speak.  My major problem is getting some Tier-1's to go for
it...Anyways I guess larger attacks than last Feb. will have to happen to
get something done?  Let's hope not...

Oh, do tell... how does the fact that you null route smurf amps stop those
amps attacking you?
