✓ 3 nameservers #6

Delegated to nsauth1.vancis.nl, nsauth2.vancis.nl, nsauth3.vancis.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.

One address family in one network

all IPv6 addresses are in 2001:4d60::/48, while the other address family is spread over several networks.

#10
✓ 2 autonomous systems #11

The nameservers are spread over: AS1126 (VANCIS - IDDQD-AS, EU): 4 addresses; AS8075 (MICROSOFT-CORP-MSN-AS-BLOCK - Microsoft Corporation, US): 1 address.
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.
