Errors (2)
  • . to lr: 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. (77.72.229.254, 147.28.0.39, 196.216.168.61, 2001:418:1::39, 2001:43f8:120::61, 2a01:3f0:0:306::53, UDP_-_EDNS0_4096_D_K)
  • . to lr: 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. (77.72.229.254, 147.28.0.39, 196.216.168.61, 2001:418:1::39, 2001:43f8:120::61, 2a01:3f0:0:306::53, UDP_-_EDNS0_4096_D_K)
Warnings (4)
  • lr/DS (alg 8, id 29984): DNSSEC specification prohibits signing with DS records that use digest algorithm 1 (SHA-1).
  • lr/DS (alg 8, id 29984): DNSSEC specification prohibits signing with DS records that use digest algorithm 1 (SHA-1).
  • lr/DS (alg 8, id 29984): DS records with digest type 1 (SHA-1) are ignored when DS records with digest type 2 (SHA-256) exist in the same RRset.
  • lr/DS (alg 8, id 29984): DS records with digest type 1 (SHA-1) are ignored when DS records with digest type 2 (SHA-256) exist in the same RRset.
