  • ietf.org/SOA: 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). (4.31.198.40, UDP_-_EDNS0_4096_D_K)

  • ietf.org/TXT: No response was received from the server over UDP (tried 6 times) until the COOKIE EDNS option was removed (however, this server appeared to respond legitimately to other queries with the COOKIE EDNS option present). (4.31.198.40, UDP_-_EDNS0_4096_D_K)
