Hello, is it possible to use some trick to configure Unbound to refuse ANY queries? It would be helpful for (intentionally) open recursors before https://tools.ietf.org/html/draft-ietf-dnsop-refuse-any is implemented. Thank you for your time. -- Petr Špaček @ CZ.NIC

Hi, generally speaking 20 % of NXDOMAIN (or even more) is about normal pattern we see in normal traffic. Blame Google Chrome and the like, they use it do detect DNS hijacking. Aggressive use of DNSSEC-validated cache will help for signed zones but there is no real 'solution' except fixing clients
