Errors (9)
- gov to iad.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. (8.44.96.33, 8.44.96.34, UDP_-_EDNS0_4096_D_KN)
- gov to iad.gov: 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. See RFC 4035, Sec. 2.2, RFC 6840, Sec. 5.11. (8.44.96.33, 8.44.96.34, UDP_-_EDNS0_4096_D_KN)
- iad.gov zone: There was an error resolving the following NS name(s) to address(es): bloodgem.iad.gov
- iad.gov/A: DNSSEC was effectively downgraded because no response was received from the server over UDP (tried 11 times) with EDNS enabled. See RFC 6891, Sec. 7, RFC 2671, Sec. 5.3. (8.44.96.33, 8.44.96.34, UDP_-_NOEDNS_)
- iad.gov/A: No response was received from the server over UDP (tried 11 times) until EDNS was disabled (however, this server appeared to respond legitimately to other queries with EDNS enabled). See RFC 6891, Sec. 6.2.6. (8.44.96.33, 8.44.96.34, UDP_-_EDNS0_4096_D_KN)
- iad.gov/A: 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. (8.44.96.33, 8.44.96.34, UDP_-_EDNS0_4096_D_KN)
- iad.gov/CNAME has errors; select the "Denial of existence" DNSSEC option to see them.
- 4ydm9lth8r.iad.gov/A has errors; select the "Denial of existence" DNSSEC option to see them.
- iad.gov/AAAA has errors; select the "Denial of existence" DNSSEC option to see them.
Warnings (4)
- iad.gov/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. See RFC 6891, Sec. 6.2.6. (8.44.96.33, 8.44.96.34, UDP_-_EDNS0_4096_D_KN)
