Description
Some DNS authoritative servers provide incorrect proofs of non-existence which correctly DNSSEC-validate but deny existence of data which actually do exist in the zone. Consequently, this causes silent resolution failures on resolvers which implement aggressive use of DNSSEC-validated cache (RFC 8198).
This talk aims to provide very short glimpse to where the breakage can be found in wild on the Internet.
