Errors (2)
  • edu to ndu.edu: 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. (216.21.18.48, 216.21.19.239, UDP_-_EDNS0_4096_D_K)
  • edu to ndu.edu: 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. See RFC 4035, Sec. 2.2, RFC 6840, Sec. 5.11. (216.21.18.48, 216.21.19.239, UDP_-_EDNS0_4096_D_K)
