Checks

✓ 3 nameservers #6

Delegated to ns1.bhosted.nl, ns3.bhosted.nl, ns4.bhosted.nl.
✓ 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 3 IPv4 /24s and 3 IPv6 /48s.
✓ 3 autonomous systems #11

The nameservers are spread over: AS20857 (TRANSIP-AS - Signet B.V., NL): 2 addresses; AS25459 (NEDZONE-AS - Eurofiber Cloud Infra B.V., NL): 2 addresses; AS49981 (WorldStream - WorldStream 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.
