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.
    #12
  • i
    Partly IPv6
    These nameservers have no IPv6 address: ns.systemec.nl, ns4.systemec.nl.

    Software version disclosed
    These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns.systemec.nl: "PowerDNS Authoritative Server 5.0.1 (built Oct 30 2025 10:38:39 by root@localhost)"; ns4.systemec.nl: "PowerDNS Authoritative Server 5.0.3 (built Feb 19 2026 15:05:24 by root@localhost)". Hide or replace the version string.

Checks

  • ✓ TTLs within range #32
    TTLs: A 10m, AAAA 10m, MX 10m, NS 10m. The NS TTL at the parent is 1h and in the zone 10m; resolvers may use either.
  • ✓ No CNAME at the apex #33
    The zone apex has no CNAME record.
  • ✓ No wildcard #34
    Names that don't exist return NXDOMAIN.

    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.
