Glue differs from the zone

The addresses at the parent (glue) differ from the addresses in the zone: ns1.iclicks.nl (glue 213.159.25.25, zone 213.159.25.25, 2a11:800::500); ns2.iclicks.nl (glue 83.96.168.8, zone 83.96.168.8, 2001:828:400:1100:29::5353); ns3.iclicks.nl (glue 149.210.134.176, zone 149.210.134.176, 2a01:7c8:aab2:2ed:5054:ff:fee7:a590). 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 3 IPv4 /24s and 3 IPv6 /48s.
✓ 3 autonomous systems #11

The nameservers are spread over: AS208537 (m3networks - M3 Groep BV, NL): 2 addresses; AS20857 (TRANSIP-AS - Signet B.V., NL): 2 addresses; AS31586 (AS-TBNLTN - 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.

Nameservers not responding

These addresses did not answer, so resolvers waste time on timeouts: ns1.iclicks.nl (2a11:800::500): read udp [2a01:4f8:1c1c:eebf::1]:45936->[2a11:800::500]:53: i/o timeout.

Every responding nameserver answers authoritatively for the zone.
✓ No recursion #16

The nameservers do not answer recursive queries for other domains.

Software version disclosed

These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.iclicks.nl: "PowerDNS Authoritative Server 4.9.17"; ns2.iclicks.nl: "PowerDNS Authoritative Server 4.9.18 (built Oct 7 2026 06:11:27 by root@localhost)"; ns3.iclicks.nl: "PowerDNS Authoritative Server 4.9.18 (built Oct 7 2026 06:11:27 by root@localhost)". Hide or replace the version string.

#17
✓ Zone transfers refused #18

No nameserver allows a zone transfer to the public.
✓ 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.

Very low TTLs

These records have a TTL below 5m, causing extra queries and slower lookups: A (1m). Low TTLs are useful just before a planned change.

#32
✓ No CNAME at the apex #33

The zone apex has no CNAME record.
i

Wildcard record

A random name under the zone resolves, so there is a wildcard (*) record. Typos and non-existent hosts resolve too, which can confuse mail and certificate checks.

#34
i

No CAA records

Without CAA records any certificate authority may issue certificates for this domain. A CAA record limits issuance to the CAs you use.
