Checks

  • ✓ 5 nameservers #6
    Delegated to dns1.name-services.com, dns2.name-services.com, dns3.name-services.com, dns4.name-services.com, dns5.name-services.com.
  • ✓ 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 2 IPv4 /24s and 2 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS15348 (TUCOWS - Tucows.com Co., CA): 4 addresses; AS32491 (TUCOWS-3 - Tucows.com Co., CA): 6 addresses.
  • i
    All nameserver names under .com
    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
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.

  • ✓ Zone transfers refused #18
    No nameserver allows a zone transfer to the public.

    Very low TTLs
    These records have a TTL below 5m, causing extra queries and slower lookups: NS (0s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 0s; resolvers may use either.
