Errors (5)
  • edu to sfasu.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. (144.96.192.192, 144.96.192.194, UDP_-_EDNS0_4096_D_KN)
  • edu to sfasu.edu: 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. (144.96.192.192, 144.96.192.194, UDP_-_EDNS0_4096_D_KN)
