Errors (9)
  • mil to dtra.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. (214.27.180.254, 214.27.184.254, UDP_-_EDNS0_4096_D_KN)
  • mil to dtra.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. (214.27.180.254, 214.27.184.254, UDP_-_EDNS0_4096_D_KN)

Warnings (14)
  • dtra.mil/DS (alg 8, id 35584): DNSSEC implementers are prohibited from implementing signing with DS algorithm 1 (SHA-1). See RFC 8624, Sec. 3.2.

  • dtra.mil/DS (alg 8, id 35584): DS records with digest type 1 (SHA-1) are ignored when DS records with digest type 2 (SHA-256) exist in the same RRset. See RFC 4509, Sec. 3.
  • dtra.mil/DS (alg 8, id 35584): DS records with digest type 1 (SHA-1) are ignored when DS records with digest type 2 (SHA-256) exist in the same RRset. See RFC 4509, Sec. 3.
  • dtra.mil/SOA: No response was received until the UDP payload size was decreased, indicating that the server might be attempting to send a payload that exceeds the path maximum transmission unit (PMTU) size. See RFC 6891, Sec. 6.2.6. (214.27.180.254, UDP_-_EDNS0_4096_D_KN)
