Errors (16)
  • dcmsa.mil zone: The following NS name(s) did not resolve to address(es): dcmsadc01.dcmsa.mil, dcmsans02.dcmsa.mil
  • dcmsa.mil zone: The server(s) responded over TCP with a malformed response or with an invalid RCODE. See RFC 1035, Sec. 4.1.1. (214.37.136.48)
  • dcmsa.mil zone: There was an error resolving the following NS name(s) to address(es): dcmsa-dc01.dcmsa.mil, dcmsa-dc02.dcmsa.mil
  • dcmsa.mil/A: No RRSIG covering the RRset was returned in the response. See RFC 4035, Sec. 3.1.1. (214.37.136.50, UDP_-_EDNS0_4096_D_KN)
  • dcmsa.mil/A: The response had an invalid RCODE (SERVFAIL). See RFC 1035, Sec. 4.1.1. (214.37.136.48, UDP_-_NOEDNS_)
  • dcmsa.mil/NS: No RRSIG covering the RRset was returned in the response. See RFC 4035, Sec. 3.1.1. (214.37.136.48, 214.37.136.50, UDP_-_EDNS0_4096_D_KN)
  • dcmsa.mil/SOA: No RRSIG covering the RRset was returned in the response. See RFC 4035, Sec. 3.1.1. (214.37.136.48, 214.37.136.50, TCP_-_EDNS0_4096_D_N, UDP_-_EDNS0_4096_D_KN, UDP_-_EDNS0_4096_D_KN_0x20)
  • dcmsa.mil/SOA: No response was received from the server over TCP (tried 5 times). See RFC 1035, Sec. 4.2. (214.37.136.48, TCP_-_NOEDNS_)
  • mil to dcmsa.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. (214.37.136.48, 214.37.136.50, UDP_-_EDNS0_4096_D_KN, UDP_-_EDNS0_512_D_KN)
  • mil to dcmsa.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. (214.37.136.48, 214.37.136.50, UDP_-_EDNS0_4096_D_KN, UDP_-_EDNS0_512_D_KN)
