• ✓ 3 nameservers #6

  Delegated to ns-1584.awsdns-06.co.uk, ns-330.awsdns-41.com, ns-763.awsdns-31.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 3 IPv4 /24s and 3 IPv6 /48s.
• i

  All nameservers in one AS

  All nameserver addresses are announced by one network operator (AS16509 (AMAZON-02 - Amazon.com, Inc., US): 6 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 3 TLDs #12

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

  Every nameserver has an IPv6 address.

  Hidden master

  The primary nameserver ns-1046.awsdns-02.org 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.

  #24
• ✓ Contact awsdns-hostmaster@amazon.com #25

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

Checks

• ✓ TTLs within range #32

  TTLs: A 5m, MX 6h, NS 2h. The NS TTL at the parent is 2d and in the zone 2h; resolvers may use either.
• ✓ No CNAME at the apex #33

  The zone apex has no CNAME record.
• i

  Wildcard record

  A random name under the zone resolves, so there is a wildcard (*) record. Typos and non-existent hosts resolve too, which can confuse mail and certificate checks.

• ✓ CAA restricts issuance #35
