✓ 6 nameservers #6

Delegated to a1-141.akam.net, a10-66.akam.net, a20-64.akam.net, a24-64.akam.net, a5-65.akam.net, a9-66.akam.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 6 IPv4 /24s and 6 IPv6 /48s.
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS21342 (AKAMAI-ASN2 - Akamai International B.V., NL): 12 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.

#11
i

All nameserver names under .net

All nameserver names are under one TLD, so a problem with that TLD also makes the nameservers unreachable. Some operators use names under two TLDs for extra resilience.

#12
✓ 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 (20s), AAAA (20s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 15m; resolvers may use either.

#32
✓ 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.

#34
i

No CAA records

Without CAA records any certificate authority may issue certificates for this domain. A CAA record limits issuance to the CAs you use.
