Hello! I'm not sure for the right wording used in $subject, but the issue is here, let me describe it.
auth-zone: name: "dom" primary: <primary-ip> zonefile: "dom.cached" for-downstream: no With this config, and with "dom" containing the following 3 records (+ all the right DNSSEC ones): a.x A 127.0.0.1 y A 127.0.0.1 b.y A 127.0.0.1 query for foo.y.dom (non-existing) return NXDOMAIN, but query for foo.x.dom (also non-existing) return TEMPFAIL, with the following in the log: unbound: [73699:0] debug: NameError response has failed to prove: covering wildcard does not exist unbound: [73699:0] debug: NODATA response failed to prove NODATA status with NSEC/NSEC3 unbound: [73699:0] info: validate(nxdomain): sec_status_bogus (with many other debugging info omitted). The difference between foo.x.dom and foo.y.dom is that the intermediate label in first case (x.dom) does not have its own records, while in the second case (y.dom) does have an A record. So for any subdomain of a label which does not have its own records but which exists, unbound fails to validate NXDOMAIN. This smells like a wrong behavior? Thanks! /mjt
