Errors (7)
  • mil to nro.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. See RFC 4035, Sec. 2.2, RFC 6840, Sec. 5.11. (209.22.180.120, 214.3.129.40, UDP_-_EDNS0_4096_D_KN)
  • mil to nro.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. See RFC 4035, Sec. 2.2, RFC 6840, Sec. 5.11. (209.22.180.120, 214.3.129.40, UDP_-_EDNS0_4096_D_KN)
  • mil zone: The server(s) were not responsive to queries over UDP. See RFC 1035, Sec. 4.2. (2608:c144:1:155::234)
