Errors (2)
  • mil to vaccines.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. (199.252.47.11, 199.252.47.75, 214.14.133.11, UDP_-_EDNS0_4096_D_KN)
  • mil to vaccines.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. (199.252.47.11, 199.252.47.75, 214.14.133.11, UDP_-_EDNS0_4096_D_KN)
Warnings (6)
  • mil/DS (alg 8, id 51349): DNSSEC specification prohibits signing with DS records that use digest algorithm 1 (SHA-1).
  • mil/DS (alg 8, id 51349): DNSSEC specification prohibits signing with DS records that use digest algorithm 1 (SHA-1).
  • mil/DS (alg 8, id 51349): DS records with digest type 1 (SHA-1) are ignored when DS records with digest type 2 (SHA-256) exist in the same RRset.
  • mil/DS (alg 8, id 51349): DS records with digest type 1 (SHA-1) are ignored when DS records with digest type 2 (SHA-256) exist in the same RRset.
  • vaccines.mil/NS: No response was received until the UDP payload size was decreased, indicating that the server might be attempting to send a payload that exceeds the path maximum transmission unit (PMTU) size. (199.252.47.11, UDP_-_EDNS0_4096_D_KN)
  • vaccines.mil/SOA: No response was received until the UDP payload size was decreased, indicating that the server might be attempting to send a payload that exceeds the path maximum transmission unit (PMTU) size. (214.14.133.11, UDP_-_EDNS0_4096_D_KN)
