There is another mitigation: everyone here should commit to filtering
customer packets at the customer premesis router (or at the dial in for
PPP/SLIP) such that it is not possible for a customer to send a packet into
the network that has an IP source address on it that is not assigned to
that customer. That is, no more lying about source addresses.

Every time I show a customer of mine how to configure a router, I 
try to educate them on this.  We need some kind of massive marketing
effort to get this out to people though.  People would do it, but nobody
knows about it.

Maybe we should get CyberPromo to spam all the technical contacts
in Internic's database to tell them how to do filtering. :)
