• ✓ 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

• ✓ Nameservers in different networks #10

  The nameservers are spread over 4 IPv4 /24s and 4 IPv6 /48s.
• i

  All nameservers in one AS

  All nameserver addresses are announced by one network operator (AS8075 (MICROSOFT-CORP-MSN-AS-BLOCK - Microsoft Corporation, US): 8 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 .com, .info, .net, .org.
• ✓ All reachable over IPv6 #13

  Every nameserver has an IPv6 address.
