Errors (6)
  • gov to dc3on.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. (66.102.236.215, 66.102.236.216, UDP_-_EDNS0_4096_D_KN)
  • gov to dc3on.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. (66.102.236.215, 66.102.236.216, UDP_-_EDNS0_4096_D_KN)
