iad.gov/DS (alg 8, id 64649)

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. (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. (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. (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). (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. (8.44.96.33, 8.44.96.34, UDP_-_EDNS0_4096_D_KN)

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. (8.44.96.33, 8.44.96.34, UDP_-_EDNS0_4096_D_KN)
