We see approximately 60-70 spoofed DDOS attacks per day at our Network Telescope: http://noc.ilan.net.il/research/riverhead/
The volume of backscatter we see on our "dark space" /16 is about 50kb/sec: http://noc.ilan.net.il/stats/TAU-GIGAPOP/riverbsc-gp1.ilan.net.il.html I have no way of proving it but I assume we see only 10% of the daily DDOS attacks that take place on the Internet since as you state - most of the attacks these days are from "100% valid and accurate source IP addresses". -Hank > The majority of the DDoS traffic that's been received here over the > past year has had 100% valid and accurate source IP addresses. > > -- > Andrew, Supernews > http://www.supernews.com >
