2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns2.wanassist.nl, web5.hsqd.nl.

#6
✓ Parent and zone agree #7

The parent delegation and the zone's NS records list the same nameservers.
!

Glue differs from the zone

The addresses at the parent (glue) differ from the addresses in the zone: ns2.wanassist.nl (glue 141.138.139.244, zone 141.138.139.244, 2a01:7c8:aaaa:5c:5054:ff:fe43:cb1a). Update the glue at your registrar.

#8
✓ 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: AS12595 (AS-XYNTA - Onworx BV, NL): 2 addresses; AS20857 (TRANSIP-AS - Signet B.V., NL): 2 addresses.

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.
