  • ✓ 8 nameservers #6
    Delegated to dns1.p09.nsone.net, dns2.p09.nsone.net, dns3.p09.nsone.net, dns4.p09.nsone.net, ns01.marketdatasystems.net, ns02.marketdatasystems.net, ns03.marketdatasystems.net, ns04.marketdatasystems.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 3 IPv4 /24s and 3 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS62597 (NSONE - NSONE Inc, US): 8 addresses; AS63911 (NETACTUATE-AS-AP - NetActuate, Inc, US): 8 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.
