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 (AS16509 (AMAZON-02 - Amazon.com, Inc., 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, .net, .org, .uk.
✓ All reachable over IPv6 #13

Every nameserver has an IPv6 address.
