  • i
    .be is a country-code TLD (ccTLD)

    #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.ucll.be, ns2.belnet.be, ns2.ucll.be, ns3.belnet.be.
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • !
    Glue differs from the zone
    The addresses at the parent (glue) differ from the addresses in the zone: ns1.ucll.be (glue 193.190.138.150, zone 193.190.138.150, 2a02:2c40:50:102::5); ns2.ucll.be (glue 193.190.138.151, zone 193.190.138.151, 2a02:2c40:50:102::6). Update the glue at your registrar.
    #8
  • ✓ 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.
