Errors (8)
  • mil to centcom.mil: 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. (214.26.71.170, 214.26.165.219, 214.27.97.204, UDP_-_EDNS0_4096_D_KN)
  • mil to centcom.mil: 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. (214.26.71.170, 214.26.165.219, 214.27.97.204, UDP_-_EDNS0_4096_D_KN)
