2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns3.firstfind.nl, ns4.firstfind.nl.

#6
!

NS sets differ

The nameservers at the parent and in the zone should be the same. Only in the zone: ns5.firstfind.net. ns3.firstfind.nl, ns4.firstfind.nl, ns5.firstfind.net report NS ns3.firstfind.nl ns4.firstfind.nl ns5.firstfind.net.

#7
✓ 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 2 IPv6 /48s.
✓ 2 autonomous systems #11

The nameservers are spread over: AS14061 (DIGITALOCEAN-ASN - DigitalOcean, LLC, US): 2 addresses; AS48635 (CLDIN-NL - Your Hosting B.V., NL): 4 addresses.
i

All nameserver names under .nl

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 (1m40s), MX (1m40s), NS (1m40s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 1m40s; 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.
