Errors (2)
  • gov to nicic.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. (149.101.80.157, 149.101.180.157, 2607:f330:5000:107f::86, 2607:f330:6000:107f::86, UDP_-_EDNS0_4096_D_KN)
  • gov to nicic.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. (149.101.80.157, 149.101.180.157, 2607:f330:5000:107f::86, 2607:f330:6000:107f::86, UDP_-_EDNS0_4096_D_KN)
Warnings (4)
  • nicic.gov/DS (alg 8, id 30079): DNSSEC specification prohibits signing with DS records that use digest algorithm 1 (SHA-1).
  • nicic.gov/DS (alg 8, id 30079): DNSSEC specification prohibits signing with DS records that use digest algorithm 1 (SHA-1).
  • nicic.gov/DS (alg 8, id 30079): DS records with digest type 1 (SHA-1) are ignored when DS records with digest type 2 (SHA-256) exist in the same RRset.
  • nicic.gov/DS (alg 8, id 30079): DS records with digest type 1 (SHA-1) are ignored when DS records with digest type 2 (SHA-256) exist in the same RRset.
