Checks

✓ 4 nameservers #6

Delegated to ns.systemec.nl, ns2.systemec.nl, ns3.systemec.nl, ns4.systemec.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 2 IPv6 /48s.
✓ 2 autonomous systems #11

The nameservers are spread over: AS31251 (NETGUARD-AS - Falco IPR BV, NL): 1 address; AS41480 (SYSTEMEC-AS - Systemec BV, NL): 5 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.

Partly IPv6

These nameservers have no IPv6 address: ns.systemec.nl, ns4.systemec.nl.
