• ✓ 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 7 IPv6 /48s.
• ✓ 2 autonomous systems #11

  The nameservers are spread over: AS20940 (AKAMAI-ASN1 - Akamai International B.V., NL): 2 addresses; AS21342 (AKAMAI-ASN2 - Akamai International B.V., NL): 14 addresses.

  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.
