✓ 4 nameservers #6

Delegated to ns-1347.awsdns-40.org, ns-135.awsdns-16.com, ns-1554.awsdns-02.co.uk, ns-627.awsdns-14.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 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.

Very low TTLs

These records have a TTL below 5m, causing extra queries and slower lookups: A (2m), AAAA (2m), MX (2m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 2d; resolvers may use either.

✓ No CNAME at the apex #33
