  • ✓ 10 nameservers #6
    Delegated to a1-91.akam.net, a13-65.akam.net, a16-65.akam.net, a20-65.akam.net, a28-65.akam.net, a3-67.akam.net, dns1.p01.nsone.net, dns2.p01.nsone.net, dns3.p01.nsone.net, dns4.p01.nsone.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 8 IPv4 /24s and 8 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS21342 (AKAMAI-ASN2 - Akamai International B.V., NL): 12 addresses; AS62597 (NSONE - NSONE 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.
