  • 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.

  • ✓ 6 nameservers #6
    Delegated to a1-63.akam.net, a11-66.akam.net, a4-67.akam.net, a6-64.akam.net, a7-65.akam.net, a8-66.akam.net.
  • ✓ 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 6 IPv4 /24s and 6 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS20940 (AKAMAI-ASN1 - Akamai International B.V., NL): 1 address; AS21342 (AKAMAI-ASN2 - Akamai International B.V., NL): 11 addresses.
  • i
    All nameserver names under .net
    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.

    Very low TTLs
    These records have a TTL below 5m, causing extra queries and slower lookups: A (20s), AAAA (20s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1d and in the zone 3h; resolvers may use either.

    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.
