Errors (13)
  • gov to peacecorps.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.
  • peacecorps.gov/AAAA: No response was received from the server over UDP (tried 12 times). See RFC 1035, Sec. 4.2. (65.205.231.223, UDP_-_NOEDNS_)
  • peacecorps.gov/DNSKEY: No response was received from the server over UDP (tried 12 times). See RFC 1035, Sec. 4.2. (65.205.231.167, 65.205.231.223, UDP_-_NOEDNS_)

  • peacecorps.gov/SOA: DNSSEC was effectively downgraded because no response was received from the server over UDP (tried 10 times) with the DO bit set. See RFC 4035, Sec. 3.2.1. (65.205.231.167, UDP_-_EDNS0_4096_)
  • peacecorps.gov/SOA: 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). See RFC 6891, Sec. 6.1.4. (65.205.231.167, UDP_-_EDNS0_4096_D_KN)
  • peacecorps.gov/SOA: No response was received from the server over UDP (tried 12 times). See RFC 1035, Sec. 4.2. (65.205.231.167, 65.205.231.223, UDP_-_NOEDNS_, UDP_-_NOEDNS__0x20)
  • peacecorps.gov/SOA: The DNSSEC records necessary to validate the response could not be retrieved from the server. See RFC 4035, Sec. 3.1.1, RFC 4035, Sec. 3.1.3. (65.205.231.167, UDP_-_EDNS0_4096_D_KN)
