  • army.mil/DNSKEY: No response was received from the server over TCP (tried 12 times). (130.114.200.6, TCP_-_EDNS0_4096_D_KN)
  • army.mil/DNSKEY: No response was received from the server over UDP (tried 12 times). (140.153.43.44, 192.82.113.7, UDP_-_EDNS0_4096_D_KN)
  • army.mil/MX: No response was received from the server over UDP (tried 4 times). (192.82.113.7, UDP_-_EDNS0_512_D_KN)
  • army.mil/NSEC3PARAM: DNSSEC was effectively downgraded because the response had an invalid RCODE (SERVFAIL) with EDNS enabled. (140.153.43.44, UDP_-_NOEDNS_)
  • army.mil/NSEC3PARAM: The DNSSEC records necessary to validate the response could not be retrieved from the server. (140.153.43.44, UDP_-_EDNS0_4096_D_KN)
  • army.mil/NSEC3PARAM: The response had an invalid RCODE (SERVFAIL) until EDNS was disabled (however, this server appeared to respond legitimately to other queries with EDNS enabled). (140.153.43.44, UDP_-_EDNS0_4096_D_KN)

  • mil to army.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.

  • army.mil/DS (alg 8, id 62140): DS records with digest type 1 (SHA-1) are ignored when DS records with digest type 2 (SHA-256) exist in the same RRset.
