2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns2.kpn.net, ns4.kpn.net.

#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.

Nameservers in one network

all IPv4 addresses are in 194.151.228.0/24; all IPv6 addresses are in 2a02:a47f:ac::/48. A single network failure takes all nameservers down; RFC 2182 recommends topologically separate networks (anycast setups are an exception).

#10
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS1136 (KPN - KPN B.V., NL): 4 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.

#11
i

All nameserver names under .net

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.

Unused DS records

These DS records match no key in the zone: key tag 9406 (SHA256), key tag 346 (SHA256), key tag 58324 (SHA256). That is normal during a key rollover; otherwise remove them.

NSEC3 with extra iterations or salt

NSEC3 uses 10 iterations and a 4-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.
