What you actually want to know is what the ingress interfaces for the
flows are. And if the ingress interface is not a p2p interface, from
which peer. For both problems quite effective solutions do exist
(ok, not really for the latter, but this is highly vendor specific).
No, what I really want to know is the source IP.
Didn't we cover this?
Given that most DDoSses are mounted via huge zombie collections, there
is not much point in knowing the real source IPs.
Yes, there are zombie armies launching DDoS from "real" IP addresses.
But that does not mean there are no spoofed-source attacks any more.
