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.

    2 nameservers
    Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns3.european-server.com, ns4.european-server.com.
    #6
  • !
    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: ns3.european-server.com, ns4.european-server.com; only in the zone: ns1.combell.eu, ns3.combell.net, ns4.combell.net. ns1.combell.eu, ns3.combell.net, ns3.european-server.com, ns4.combell.net, ns4.european-server.com report NS ns1.combell.eu ns3.combell.net ns4.combell.net.
    #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 different networks #10
    The nameservers are spread over 3 IPv4 /24s and 3 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS28747 (EASYHOST-COLO-AS - Easyhost BVBA, BE): 4 addresses; AS34762 (COMBELL-AS - Combell NV, BE): 6 addresses.
  • i
    All nameserver names under .com
    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.
