This presentation looks at the previous analysis of use of aggressive NSEC caching (Petr Spacek, OARC, March 2018) and compares the results obtains in those tests to the results obtained in a large scale study of NSEC caching behaviour in the Internet. The results of this second study point to some issues with the interaction between NSEC caching and DNS load balancer behaviour.
