    #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 in the zone: ns.rtbf.be. ns.rtbf.be, ns1.belnet.be, ns1.rtbf.be, ns2.belnet.be, ns2.rtbf.be, ns3.belnet.be report NS ns.rtbf.be ns1.belnet.be ns1.rtbf.be ns2.belnet.be ns2.rtbf.be ns3.belnet.be.
    #7
  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: ns1.rtbf.be, ns2.rtbf.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 5 IPv4 /24s and 2 IPv6 /48s.
  • ✓ 3 autonomous systems #11
    The nameservers are spread over: AS2611 (BELNET - BELNET, BE): 4 addresses; AS62058 (RTBF - ETSPUBLI RADIO-TELEVISION BELGE DE LA COMMUNAUTE FRANCAISE, BE): 3 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: ns.rtbf.be, ns1.rtbf.be, ns2.rtbf.be.
