Since version 4.5 PowerDNS Recursor implements an aggressive NSEC/NSEC3 cache, as described in RFC8198. Other recursive resolvers also have an aggressive NSEC/NSEC3 cache implementation.
We will discuss the effectiveness of an aggressive cache for both NSEC and NSEC3 zones. It turns out that especially the NSEC3 results need extra study.
