  • ✓ 7 nameservers #6
    Delegated to ns1.gothru.ca, ns2.gothru.ca, ns3.gothru.ca, ns4.gothru.ca, ns5.gothru.ca, ns6.gothru.ca, ns7.gothru.ca.
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • ✓ No glue needed #8
    All nameservers are outside the zone, so no glue records are needed.
  • ✓ All names resolve #9
    Every nameserver name has an address and is not an alias.
  • ✓ Nameservers in different networks #10
    The nameservers are spread over 7 IPv4 /24s and 5 IPv6 /48s.
  • ✓ 6 autonomous systems #11
    The nameservers are spread over: AS16276 (OVH - OVH SAS, FR): 4 addresses; AS272696 (AS272696 - HOSTING NOW NET LTDA, BR): 2 addresses; AS33333 (OBJX - objx.net, LLC, US): 1 address; AS43969 (PRINODE - Prinode AB, SE): 1 address; AS62068 (SpectraIP - SpectraIP B.V., NL): 1 address; AS63473 (HOSTHATCH - HostHatch, LLC, US): 3 addresses.
  • i
    All nameserver names under .ca
    All nameserver names are under one TLD, so a problem with that TLD also makes the nameservers unreachable. Some operators use names under two TLDs for extra resilience.
    #12
  • i
    Partly IPv6
    These nameservers have no IPv6 address: ns6.gothru.ca, ns7.gothru.ca.

    Very low TTLs
    These records have a TTL below 5m, causing extra queries and slower lookups: A (2m), AAAA (2m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 5m; resolvers may use either.

  • ✓ No CNAME at the apex #33
    The zone apex has no CNAME record.
  • ✓ No wildcard #34
    Names that don't exist return NXDOMAIN.

    No CAA records
    Without CAA records any certificate authority may issue certificates for this domain. A CAA record limits issuance to the CAs you use.
