Checks

  • ✓ 3 nameservers #6
    Delegated to ns2.belastingdienst.nl, ns3.belastingdienst.nl, ns4.belastingdienst.nl.
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: ns2.belastingdienst.nl, ns3.belastingdienst.nl, ns4.belastingdienst.nl.
  • ✓ All names resolve #9
    Every nameserver name has an address and is not an alias.
  • i
    One address family in one network
    all IPv6 addresses are in 2a04:9a01:1002::/48, while the other address family is spread over several networks.
    #10
  • ✓ 3 autonomous systems #11
    The nameservers are spread over: AS24595 (ASBKN - Belastingdienst, NL): 2 addresses; AS34663 (ASBELASTINGDIENST - Belastingdienst, NL): 2 addresses; AS48037 (SSO-ICT - SSC-ICT Haaglanden, NL): 1 address.
  • i
    All nameserver names under .nl
    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: ns4.belastingdienst.nl.
