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.

  • !
    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: ns.hzs.be, ns1.belnet.be, ns2.belnet.be; only in the zone: mercator.hzs.be, ns.belnet.be. mercator.hzs.be, ns.belnet.be, ns.hzs.be, ns1.belnet.be, ns2.belnet.be report NS mercator.hzs.be ns.belnet.be.
    #7
  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: ns.hzs.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 3 IPv4 /24s and 2 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS2611 (BELNET - BELNET, BE): 10 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
  • i
    Partly IPv6
    These nameservers have no IPv6 address: mercator.hzs.be, ns.hzs.be.

    Unusual SOA timers
    refresh 5m is outside 20m–1d; retry 10m should be shorter than refresh 5m; expire 10m is shorter than 7d; secondaries stop answering too soon when the primary is down; expire 10m must be longer than refresh + retry. Current values: refresh 5m, retry 10m, expire 10m, negative TTL 10m.

  • i
    Hidden master
    The primary nameserver hzs.be is not listed as a nameserver: a hidden master that only feeds the public secondaries. That is a common setup; make sure it is not reachable for zone transfers from outside.

  • ✓ Contact hostmaster@hzs.be #25

Checks

  • ✓ TTLs within range #32
    TTLs: A 10m, MX 10m, NS 10m. The NS TTL at the parent is 1d 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.
  • 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.
