    #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

  • ✓ 5 nameservers #6
    Delegated to ns1.belnet.be, ns1.unamur.be, ns2.belnet.be, ns2.unamur.be, ns3.belnet.be.
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: ns1.unamur.be, ns2.unamur.be.
  • ✓ 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 4 IPv4 /24s and 3 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS2611 (BELNET - BELNET, BE): 8 addresses; AS8674 (NETNOD-IX - Netnod AB, SE): 2 addresses.
  • 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
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.

Checks

  • ✓ All respond #14
    All 10 nameserver addresses answered.
  • ✓ All authoritative #15
    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.unamur.be: "PowerDNS Authoritative Server 4.9.17 (built Aug 5 2026 13:33:52 by root@localhost)"; ns2.unamur.be: "PowerDNS Authoritative Server 4.9.17 (built Aug 5 2026 13:33:52 by root@localhost)". Hide or replace the version string.
    #17
  • ✓ Zone transfers refused #18
    No nameserver allows a zone transfer to the public.
  • ✗
    No DNS over TCP
    DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: ns1.unamur.be (138.48.4.5): dial tcp 138.48.4.5:53: i/o timeout; ns1.unamur.be (2001:6a8:3900:4::5): dial tcp [2001:6a8:3900:4::5]:53: i/o timeout; ns2.unamur.be (138.48.4.11): dial tcp 138.48.4.11:53: i/o timeout; ns2.unamur.be (2001:6a8:3900:4::b): dial tcp [2001:6a8:3900:4::b]:53: i/o timeout.
    #19
  • ✓ EDNS supported #20
    All nameservers support EDNS(0).
  • ✓ Public addresses #21
    All nameserver addresses are publicly routable.
