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. -- Rob Thomas Team Cymru http://www.cymru.com/ ASSERT(coffee != empty);
