  • . to au: No valid RRSIGs made by a key corresponding to a DS RR were found covering the DNSKEY RRset, resulting in no secure entry point (SEP) into the zone. See RFC 4035, Sec. 2.2, RFC 6840, Sec. 5.11. (65.22.196.1, 65.22.197.1, 65.22.198.1, 65.22.199.1, 2a01:8840:be::1, 2a01:8840:bf::1, 2a01:8840:c0::1, 2a01:8840:c1::1, UDP_-_EDNS0_4096_D_KN)
  • . to au: The DS RRset for the zone included algorithm 8 (RSASHA256), but no DS RR matched a DNSKEY with algorithm 8 that signs the zone's DNSKEY RRset.
