  • gov to twai.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. (199.169.192.28, 199.169.194.28, 2605:3100:fffc:100::7, 2605:3100:fffd:100::7, UDP_-_EDNS0_4096_D_K)
  • gov to twai.gov: The DS RRset for the zone included algorithm 7 (RSASHA1NSEC3SHA1), but no DS RR matched a DNSKEY with algorithm 7 that signs the zone's DNSKEY RRset.
