Errors (11)
  • cncsoig.gov zone: The server(s) were not responsive to queries over TCP. See RFC 1035, Sec. 4.2. (198.6.1.65)
  • cncsoig.gov/DNSKEY: No response was received from the server over UDP (tried 12 times). See RFC 1035, Sec. 4.2. (198.6.1.65, UDP_-_EDNS0_4096_D_KN)
  • cncsoig.gov/SOA: No response was received from the server over TCP (tried 3 times). See RFC 1035, Sec. 4.2. (198.6.1.65, TCP_-_EDNS0_4096_D_N)
  • gov to cncsoig.gov: 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. (198.6.1.18, TCP_-_EDNS0_4096_D_KN)
  • gov to cncsoig.gov: The DS RRset for the zone included algorithm 7 (RSASHA1NSEC3SHA1), but no DS RR matched a DNSKEY with algorithm 7 that signs the zone's DNSKEY RRset. See RFC 4035, Sec. 2.2, RFC 6840, Sec. 5.11. (198.6.1.18, TCP_-_EDNS0_4096_D_KN)
