2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: nszero1.axc.nl, nszero2.axc.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.
✓ Nameservers in different networks #10

The nameservers are spread over 2 IPv4 /24s and 2 IPv6 /48s.
✓ 2 autonomous systems #11

The nameservers are spread over: AS14061 (DIGITALOCEAN-ASN - DigitalOcean, LLC, US): 2 addresses; AS48635 (CLDIN-NL - Your Hosting B.V., NL): 2 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.
