Description
Unusual DNS query patterns have been the focus of many recent talks that have examined the sources, targets and intent of this
traffic, as well as the impact seen by authoritative servers and resolvers alike.
Over the past year ISC has been trialling experimental recursive client rate limiting techniques in BIND to limit impact of this unwanted traffic on both servers and DNS clients.
This talk recaps some of the problems that can be encountered and then reviews of the effectiveness of the experimental techniques, including results from live production environments.
