Hi, Steve.
] So -- I'd like people to re-examine the question. Does anyone have more
] recent data on the frequency of bogons as a percentage of attack
] packets? What would that number look like if you filtered just the
] obvious -- the ranges given above, plus the RFC 1918 prefixes? Are
] your defenses against non-spoofed attacks really helped by the extra
] filtering?
Great question, and we're eager to hear the results as well. Our
study is well past its prime, to be sure.
Thanks,
Rob.
