2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns1.tikklik.nl, ns2.tikklik.com.

#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.

One address family in one network

all IPv6 addresses are in 2a00:1bd0:740::/48, while the other address family is spread over several networks.

#10

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS39704 (CJ2-AS - CJ2 Hosting 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
✓ Nameserver names under 2 TLDs #12

Nameserver names use the TLDs .com, .nl.
✓ All reachable over IPv6 #13

Every nameserver has an IPv6 address.

✓ 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.
