  • org to icann.org: 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. (199.4.138.53, 199.43.133.53, 199.43.134.53, 199.43.135.53, 2001:500:89::53, 2001:500:8d::53, 2001:500:8e::53, 2001:500:8f::53, UDP_0_EDNS0_32768_4096)
  • org to icann.org: 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.
