0.7.4.0.1.0.0.2.ip6.arpa zone: The server(s) were not responsive to queries over UDP. See RFC 1035, Sec. 4.2. (216.66.80.18)
0.7.4.0.1.0.0.2.ip6.arpa/NS: The UDP connection was refused (ECONNREFUSED). See RFC 1035, Sec. 4.2. (216.66.80.18, UDP_-_EDNS0_4096_D_KN)
4.0.1.0.0.2.ip6.arpa to 0.7.4.0.1.0.0.2.ip6.arpa: 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. (2001:500:f0::63, UDP_-_NOEDNS_)
4.0.1.0.0.2.ip6.arpa to 0.7.4.0.1.0.0.2.ip6.arpa: 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. (2001:500:f0::63, UDP_-_EDNS0_4096_D_KN)
4.0.1.0.0.2.ip6.arpa to 0.7.4.0.1.0.0.2.ip6.arpa: 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. (2001:500:f0::63, UDP_-_EDNS0_4096_D_KN)
4.0.1.0.0.2.ip6.arpa/DNSKEY: No response was received from the server over UDP (tried 4 times). See RFC 1035, Sec. 4.2. (2001:500:f0::63, UDP_-_EDNS0_512_D_KN)
4.0.1.0.0.2.ip6.arpa/SOA: 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. (2001:500:f0::63, UDP_-_EDNS0_4096_D_KN)
