• ✓ 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

• i

  All nameservers in one AS

  All nameserver addresses are announced by one network operator (AS12008 (VERCARA - Vercara, LLC, US): 12 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.

  #11
• ✓ Nameserver names under 4 TLDs #12

  Nameserver names use the TLDs .info, .net, .org, .uk.
• ✓ All reachable over IPv6 #13

  Every nameserver has an IPv6 address.
