Re: Who does source address validation? (was Re: what's that smell?)

Why is it hard to believe that a large amount of RFC-1918 sourced traffic is floating around the net? Because if 20% of all people generate this crap (which is a huge number) it must be 90% of their traffic to get at 18%. How can someone generate so much useless traffic and keep doing it, too?

funny question from someone who reads this mailing list :-)
