Errors (4)
  • gov to vcf.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. See RFC 4035, Sec. 2.2, RFC 6840, Sec. 5.11. (149.101.80.157, 149.101.180.157, 2607:f330:5000:107f::86, 2607:f330:6000:107f::86, UDP_-_EDNS0_4096_D_K)
  • gov to vcf.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. See RFC 4035, Sec. 2.2, RFC 6840, Sec. 5.11. (149.101.80.157, 149.101.180.157, 2607:f330:5000:107f::86, 2607:f330:6000:107f::86, UDP_-_EDNS0_4096_D_K)

Warnings (6)
  • gov/DS (alg 8, id 7698): DNSSEC implementers are prohibited from implementing signing with DS algorithm 1 (SHA-1). See RFC 8624, Sec. 3.2.

  • gov/DS (alg 8, id 7698): DS records with digest type 1 (SHA-1) are ignored when DS records with digest type 2 (SHA-256) exist in the same RRset. See RFC 4509, Sec. 3.
