Description
Experiences of 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.
Last year, ISC proposed and then started trialling experimental recursive client rate limiting techniques in BIND, with the intent of limiting the impact of this unwanted traffic on both servers and DNS clients alike.
This talk briefly recaps some of the problems that can be encountered and then presents a review of the effectiveness of the techniques that were introduced, along with results from live production environments.
