✓ 3 nameservers #6

Delegated to ns1.hypernode.com, ns2.hypernode.com, ns3.hypernode.com.
✓ 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 0 IPv6 /48s.
✓ 2 autonomous systems #11

The nameservers are spread over: AS16509 (AMAZON-02 - Amazon.com, Inc., US): 2 addresses; AS31586 (AS-TBNLTN - Signet B.V., NL): 1 address.
i

All nameserver names under .com

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
!

No IPv6

None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.

Very low TTLs

These records have a TTL below 5m, causing extra queries and slower lookups: A (1m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 6h21m19s; resolvers may use either.

#32
✓ No CNAME at the apex #33

The zone apex has no CNAME record.
✓ No wildcard #34

Names that don't exist return NXDOMAIN.

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.
