Errors (3)
  • tigta.gov/TXT: DNSSEC was effectively downgraded because the response had an invalid RCODE (SERVFAIL) with EDNS enabled. (2606:4700:52::ac40:346e, UDP_-_NOEDNS_)
  • tigta.gov/TXT: The DNSSEC records necessary to validate the response could not be retrieved from the server. (2606:4700:52::ac40:346e, UDP_-_EDNS0_4096_D_KN)
  • tigta.gov/TXT: The response had an invalid RCODE (SERVFAIL) until EDNS was disabled (however, this server appeared to respond legitimately to other queries with EDNS enabled). (2606:4700:52::ac40:346e, UDP_-_EDNS0_4096_D_KN)
Warnings (1)
  • tigta.gov/DNSKEY: The Authoritative Answer (AA) flag was not set in the response. (172.64.52.110, 172.64.53.149, 2606:4700:52::ac40:346e, 2606:4700:5a::ac40:3595, UDP_-_EDNS0_512_D_KN)
