If one receives a packet, it's either from the supposed source or a network that allows spoofing. If no networks allow spoofing, it came from the supposed source. SD> [P]eople don't complain to the source of spoofed packet. SD> People complain to IANA about attacks coming from Net-10. They complain to the perceived source. Many Internet users are shocked at how trivial it is to forge email/packet sources; I guess they're used to services like caller ID where the end user isn't [traditionally] given the power to spoof. Then there's postal mail. At least sending spoofed packets is more costly than IP, and end-user packets frequently are tagged with an ingress label.
