Errors (2)
  • mil to dia.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. (198.201.23.26, 214.3.138.10, 214.3.138.13, UDP_-_EDNS0_4096_D_KN)
  • mil to dia.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. (198.201.23.26, 214.3.138.10, 214.3.138.13, UDP_-_EDNS0_4096_D_KN)
Warnings (5)
  • dia.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. (214.3.138.10, UDP_-_EDNS0_4096_D_KN)
  • 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.
