Errors (4)
  • com to gb.com: 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. (97.74.105.46, 173.201.73.46, 2603:5:2194::2e, 2603:5:2294::2e, UDP_-_EDNS0_4096_D_K, UDP_-_EDNS0_512_D_K)
  • com to gb.com: 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. (97.74.105.46, 173.201.73.46, 2603:5:2194::2e, 2603:5:2294::2e, UDP_-_EDNS0_4096_D_K, UDP_-_EDNS0_512_D_K)

  • gb.com/DS (alg 7, id 52307): DNSSEC specification prohibits signing with DS records that use digest algorithm 1 (SHA-1).
  • gb.com/DS (alg 7, id 52307): DNSSEC specification prohibits signing with DS records that use digest algorithm 1 (SHA-1).
  • gb.com/DS (alg 7, id 52307): DS records with digest type 1 (SHA-1) are ignored when DS records with digest type 2 (SHA-256) exist in the same RRset.
