    Delegated to ns1.rtvoost.nl, ns2.rtvoost.nl, ns3.rtvoost.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: ns1.rtvoost.nl, ns2.rtvoost.nl, ns3.rtvoost.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 2001:1690:100::/48, while the other address family is spread over several networks.
    #10
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS20847 (PREVIDER-AS - Previder B.V., NL): 5 addresses; AS57325 (AS204765 - 123Telcom BV trading as Partell, 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
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.
