2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns-1939.awsdns-50.co.uk, ns-291.awsdns-36.com.

#6
✓ 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 2 IPv4 /24s and 2 IPv6 /48s.
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS16509 (AMAZON-02 - Amazon.com, Inc., US): 4 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 2 TLDs #12

Nameserver names use the TLDs .com, .uk.
✓ All reachable over IPv6 #13

Every nameserver has an IPv6 address.

Hidden master

The primary nameserver ns-538.awsdns-03.net is not listed as a nameserver: a hidden master that only feeds the public secondaries. That is a common setup; make sure it is not reachable for zone transfers from outside.

✓ Contact awsdns-hostmaster@amazon.com #25

The SOA RNAME awsdns-hostmaster.amazon.com means awsdns-hostmaster@amazon.com.
