  • dtic.mil zone: The following NS name(s) did not resolve to address(es): ns1.dtic.mil
  • dtic.mil zone: The server(s) were not responsive to queries over TCP. See RFC 1035, Sec. 4.2. (140.18.188.250, 140.18.189.250)

  • dtic.mil/NS: DNSSEC was effectively downgraded because no response was received from the server over UDP (tried 11 times) with EDNS enabled. See RFC 6891, Sec. 7, RFC 2671, Sec. 5.3. (140.18.189.250, UDP_-_NOEDNS_)
  • dtic.mil/NS: No response was received from the server over UDP (tried 11 times) until EDNS was disabled (however, this server appeared to respond legitimately to other queries with EDNS enabled). See RFC 6891, Sec. 6.2.6. (140.18.189.250, UDP_-_EDNS0_4096_D_KN)
  • dtic.mil/NS: No response was received from the server over UDP (tried 12 times). See RFC 1035, Sec. 4.2. (140.18.188.250, UDP_-_NOEDNS_)
  • dtic.mil/NS: The DNSSEC records necessary to validate the response could not be retrieved from the server. See RFC 4035, Sec. 3.1.1, RFC 4035, Sec. 3.1.3. (140.18.189.250, UDP_-_EDNS0_4096_D_KN)

  • mil to dtic.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.
