2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns01.mostware.nl, ns02.mostware.nl.

#6
✓ 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.
i

One address family in one network

all IPv6 addresses are in 2a01:111:f100::/48, while the other address family is spread over several networks.

#10
✓ 2 autonomous systems #11

The nameservers are spread over: AS8069 (MICROSOFT-CORP-MSN-AS-BLOCK - Microsoft Corporation, US): 1 address; AS8075 (MICROSOFT-CORP-MSN-AS-BLOCK - Microsoft Corporation, US): 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.

#12
✓ All reachable over IPv6 #13

Every nameserver has an IPv6 address.

Software version disclosed

These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns01.mostware.nl: "9.16.27-Debian"; ns02.mostware.nl: "9.16.27-Debian". Hide or replace the version string.

#17
✓ Zone transfers refused #18

No nameserver allows a zone transfer to the public.
✓ TCP supported #19

All nameservers answer over TCP.
✓ EDNS supported #20

All nameservers support EDNS(0).
✓ Public addresses #21

All nameserver addresses are publicly routable.

NSEC3 with extra iterations or salt

NSEC3 uses 10 iterations and a 0-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.
