Errors (5)
  • gov to fan.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. (2.16.40.67, 23.74.25.65, 96.7.49.66, 184.26.161.64, 184.85.248.64, 193.108.91.63, 2600:1401:2::3f, 2600:1403:a::43, 2600:1408:1c::42, 2600:1480:1800::40, 2600:1480:b800::41, 2a02:26f0:117::40, UDP_-_EDNS0_4096_D_KN)
  • gov to fan.gov: 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.
