Checks

✓ 3 nameservers #6

Delegated to ns1.caveo.nl, ns2.caveo.nl, ns3.caveo.nl.
✓ 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 2 IPv6 /48s.
✓ 2 autonomous systems #11

The nameservers are spread over: AS20857 (TRANSIP-AS - Signet B.V., NL): 2 addresses; AS24642 (NL-CAVEO - Caveo Internet BV, NL): 3 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.

NSEC3 with extra iterations or salt

NSEC3 uses 1 iteration and a 1-byte salt. RFC 9276 recommends 0 iterations and no salt: extra iterations cost resolvers CPU and add no real protection, and some validators treat high counts as insecure.
