Errors (2)
  • gov to ioss.gov: 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. (8.44.96.33, 8.44.96.34, UDP_-_EDNS0_4096_D_KN)
  • gov to ioss.gov: 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. (8.44.96.33, 8.44.96.34, UDP_-_EDNS0_4096_D_KN)
Warnings (4)
  • ioss.gov/DS (alg 8, id 45124): DNSSEC specification prohibits signing with DS records that use digest algorithm 1 (SHA-1).
  • ioss.gov/DS (alg 8, id 45124): DNSSEC specification prohibits signing with DS records that use digest algorithm 1 (SHA-1).
  • ioss.gov/DS (alg 8, id 45124): DS records with digest type 1 (SHA-1) are ignored when DS records with digest type 2 (SHA-256) exist in the same RRset.
  • ioss.gov/DS (alg 8, id 45124): DS records with digest type 1 (SHA-1) are ignored when DS records with digest type 2 (SHA-256) exist in the same RRset.
