Errors (29)
  • aging.gov zone: The server(s) responded over TCP with a malformed response or with an invalid RCODE. See RFC 1035, Sec. 4.1.1. (158.74.35.11, 2607:f220:0:1::3a)
  • aging.gov/A: DNSSEC was effectively downgraded because the response had an invalid RCODE (SERVFAIL) with EDNS enabled. See RFC 6891, Sec. 7, RFC 2671, Sec. 5.3. (2607:f220:0:1::3b, UDP_-_NOEDNS_)

  • gov to aging.gov: 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. (158.74.35.11, UDP_-_NOEDNS_)
  • gov to aging.gov: The DS RRset for the zone included algorithm 13 (ECDSAP256SHA256), but no DS RR matched a DNSKEY with algorithm 13 that signs the zone's DNSKEY RRset. See RFC 4035, Sec. 2.2, RFC 6840, Sec. 5.11. (158.74.35.11, UDP_-_NOEDNS_)
