Errors (5)
  • edu to educom.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. (64.92.222.136, UDP_0_EDNS0_32768_4096, UDP_0_EDNS0_32768_512)
  • edu to educom.edu: The DS RRset for the zone included algorithm 3 (DSA), but no DS RR matched a DNSKEY with algorithm 3 that signs the zone's DNSKEY RRset. (64.92.222.136, UDP_0_EDNS0_32768_4096, UDP_0_EDNS0_32768_512)
  • edu to educom.edu: The DS RRset for the zone included algorithm 5 (RSASHA1), but no DS RR matched a DNSKEY with algorithm 5 that signs the zone's DNSKEY RRset. (64.92.222.136, UDP_0_EDNS0_32768_4096, UDP_0_EDNS0_32768_512)
