I don't think the measurement would show usable results, as you don't know if the cpe at the probe would block unknown sources or the provider. For example at my home the v4 connection uses the provider owned cpe nat and v6 would go through my firewall as the sixxs tunnel terminate on it. How would you know where the anti spoofing is implemented? Gesendet von meinem BlackBerry Originalnachricht Von: Peter Koch Gesendet: Dienstag, 17.

Could we detect probe hosts who do not deploy outgoing filtering and accept spoofed traffic?
while this may sound tempting, I think it would be more helpful in the long run to maintain atlas probes as a tool to map the Internet rather than as "spy in the house". -Peter
