Errors (2)
  • gov to itis.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. (2.16.130.67, 23.74.25.66, 84.53.139.67, 95.100.173.65, 184.85.248.64, 193.108.91.88, 2600:1401:2::58, 2600:1480:1::43, 2600:1480:9800::43, 2600:1480:b800::42, 2600:1480:d800::41, 2a02:26f0:117::40, UDP_-_EDNS0_4096_D_KN, UDP_-_EDNS0_512_D_KN)
  • gov to itis.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.
