Errors (16)
  • gov to niosh.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. (198.246.96.61, 198.246.96.92, 198.246.125.10, UDP_-_EDNS0_4096_D_KN)
  • gov to niosh.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. See RFC 4035, Sec. 2.2, RFC 6840, Sec. 5.11. (198.246.96.61, 198.246.96.92, 198.246.125.10, UDP_-_EDNS0_4096_D_KN)
