Hello,

Lutz Donnerhacke implemented DNS-Dampening.
http://lutz.donnerhacke.de/eng/Blog/DNS-Dampening

The implementation is available as patch for BIND9 only.
He told me that there is an other method preferred by the nsd developer.
It's called "Response Rate Limiting".

May one describe the idea behind rate limiting and compare it with Lutz' solution?

Thanks.
