Errors (6)
  • it/DS (alg 10, id 41901): 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. (192.33.4.12, UDP_-_EDNS0_4096_)
  • it/DS (alg 10, id 41901): 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. (192.33.4.12, UDP_-_EDNS0_4096_)
  • it/DS (alg 10, id 41901): 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. (192.33.4.12, UDP_-_EDNS0_4096_D_KN)
