Hi, NANOGers.
] I assert this is not the case. A significant percentage of DDoS attacks use
] legitimate source IP addresses. When there are thousands of throw-away hosts
I track several botnets per week, and a large amount of DDoS per week.
Only around 20% (or a bit less) of all the attacks I log use spoofed
source addresses.
Does anti-spoofing help? Yes. It is but one of many mitigation
strategies.
Thanks,
Rob.
