I'll put it another way. Any provider that does not police their customer traffic has no business whining about DoS
Most of us prevent their customers from sending out spoofed traffic.
77% of all networks seem to think so.
However the remaining networks allow spoofed traffic to egress their networks.
When that traffic enters my network, I have no method whatsoever to
differentiate it from any other traffic.
I could ask my upstream where they see it coming from, which will be
quite hard if they do not have pretty fancy systems.
But if they receive it from a peer, I am as good as lost in trying to
find the culprit.
