  • ✓ 4 nameservers #6
    Delegated to ns-146-b.gandi.net, ns-169-a.gandi.net, ns-211-c.gandi.net, z.dns.gandi.net.
  • ✓ 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 5 IPv4 /24s and 4 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS13335 (CLOUDFLARENET - Cloudflare, Inc., US): 4 addresses; AS209453 (GANDI-LIVEDNS - GANDI SAS, FR): 6 addresses.
  • i
    All nameserver names under .net
    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.
