  • ipv6-only.tlund.se zone: There was an error resolving the following NS name(s) to address(es): ns.ipv6-only.tlund.se
  • ipv6-only.tlund.se/A: No response was received from the server over UDP (tried 12 times). See RFC 1035, Sec. 4.2. (2001:67c:1898:2::53, UDP_-_NOEDNS_)
  • ipv6-only.tlund.se/NS: No response was received from the server over UDP (tried 12 times). See RFC 1035, Sec. 4.2. (2001:67c:1898:2::53, UDP_-_NOEDNS_)

  • tlund.se to ipv6-only.tlund.se: 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. See RFC 4035, Sec. 2.2, RFC 6840, Sec. 5.11.
