Errors (13)
  • edu to uofk.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. (196.202.131.180, UDP_-_EDNS0_4096_D_K, UDP_-_EDNS0_512_D_K)
  • edu to uofk.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. (196.202.131.180, UDP_-_EDNS0_4096_D_K, UDP_-_EDNS0_512_D_K)
