Errors (3)
  • dau.mil/DNSKEY (alg 8, id 29161): The DNSKEY RR was not found in the DNSKEY RRset returned by one or more servers. (214.25.1.174, UDP_-_EDNS0_4096_D_KN)
  • mil to dau.mil: 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. (214.25.1.174, UDP_-_EDNS0_4096_D_KN)
  • mil to dau.mil: 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. (214.25.1.174, UDP_-_EDNS0_4096_D_KN)
