Errors (2)
  • com to express-scripts.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. See RFC 4035, Sec. 2.2, RFC 6840, Sec. 5.11. (167.18.104.150, 167.211.104.150, TCP_-_EDNS0_4096_D_KN)
  • com to express-scripts.com: 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. (167.18.104.150, 167.211.104.150, TCP_-_EDNS0_4096_D_KN)

  • express-scripts.com/DS (alg 8, id 63919): 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.
