Checks

  • i
    .be is a country-code TLD (ccTLD)
    Country-code TLD: governed by its local registry under national policy, not by an ICANN contract. Registrar accreditation, dispute resolution and RDAP/WHOIS rules are set by the registry.
    #1
  • ✓ TLD delegated and signed #2
    .be is delegated in the root zone and DNSSEC-signed.
  • i
    Registration data not available
    No registration data via RDAP: the registry of .be offers no RDAP service. Many ccTLD registries don't offer RDAP; check the registry's WHOIS instead.

Checks

  • i
    2 nameservers
    Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns1.milieuinfo.be, ns2.milieuinfo.be.
    #6
  • !
    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: ns1.milieuinfo.be, ns2.milieuinfo.be; only in the zone: ns1.omgevingvlaanderen.be, ns2.omgevingvlaanderen.be. ns1.milieuinfo.be, ns1.omgevingvlaanderen.be, ns2.milieuinfo.be, ns2.omgevingvlaanderen.be report NS ns1.omgevingvlaanderen.be ns2.omgevingvlaanderen.be.
    #7
  • ✓ 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 one network
    all IPv4 addresses are in 193.58.156.0/24. A single network failure takes all nameservers down; RFC 2182 recommends topologically separate networks (anycast setups are an exception).
    #10
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS2611 (BELNET - BELNET, BE): 4 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.
    #11
  • i
    All nameserver names under .be
    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
  • !
    No IPv6
    None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13

  • ✓ All respond #14
    All 4 nameserver addresses answered.

    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.milieuinfo.be: "PowerDNS Authoritative Server 5.1.4 (built Aug 5 2026 13:12:37 by root@localhost)"; ns1.omgevingvlaanderen.be: "PowerDNS Authoritative Server 5.1.4 (built Aug 5 2026 13:12:37 by root@localhost)"; ns2.milieuinfo.be: "PowerDNS Authoritative Server 5.1.4 (built Aug 5 2026 13:12:37 by root@localhost)"; ns2.omgevingvlaanderen.be: "PowerDNS Authoritative Server 5.1.4 (built Aug 5 2026 13:12:37 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.
