  • usfj.mil/NSEC3PARAM: DNSSEC was effectively downgraded because no response was received from the server over UDP (tried 10 times) with the DO bit set. (199.211.150.66, UDP_-_EDNS0_4096_)
  • usfj.mil/NSEC3PARAM: No response was received from the server over UDP (tried 10 times) until the DO EDNS flag was cleared (however, this server appeared to respond legitimately to other queries with the DO EDNS flag set). (199.211.150.66, UDP_-_EDNS0_4096_D_KN)
  • usfj.mil/NSEC3PARAM: The DNSSEC records necessary to validate the response could not be retrieved from the server. (199.211.150.66, UDP_-_EDNS0_4096_D_KN)

  • mil to usfj.mil: The following NS name(s) were found in the delegation NS RRset (i.e., in the mil zone), but not in the authoritative NS RRset: pnocxns1.pr.navy.mil, pnocxns2.pr.navy.mil
  • usfj.mil/DS (alg 8, id 58520): DNSSEC specification prohibits signing with DS records that use digest algorithm 1 (SHA-1).
  • usfj.mil/DS (alg 8, id 58520): DNSSEC specification prohibits signing with DS records that use digest algorithm 1 (SHA-1).
  • usfj.mil/DS (alg 8, id 58520): DS records with digest type 1 (SHA-1) are ignored when DS records with digest type 2 (SHA-256) exist in the same RRset.

  • usfj.mil/NSEC3PARAM: No response was received from the server over UDP (tried 7 times) until the NSID EDNS option was removed (however, this server appeared to respond legitimately to other queries with the NSID EDNS option present). (199.211.150.67, UDP_-_EDNS0_4096_D_KN)
  • usfj.mil/TXT: 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. (199.211.150.67, UDP_-_EDNS0_4096_D_KN)
