    2 nameservers
    Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns01.rocmondriaan.nl, ns02.rocmondriaan.nl.
    #6
  • !
    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only in the zone: ns1.surfnet.nl, ns1.zurich.surf.net, ns2.surfnet.nl, ns3.surfnet.nl. ns01.rocmondriaan.nl, ns02.rocmondriaan.nl, ns1.surfnet.nl, ns1.zurich.surf.net, ns2.surfnet.nl, ns3.surfnet.nl report NS ns01.rocmondriaan.nl ns02.rocmondriaan.nl ns1.surfnet.nl ns1.zurich.surf.net ns2.surfnet.nl ns3.surfnet.nl.
    #7
  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: ns01.rocmondriaan.nl, ns02.rocmondriaan.nl.
  • ✓ 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 4 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS1103 (SURFNET-NL - SURF B.V., NL): 8 addresses; AS559 (Switch - SWITCH, CH): 2 addresses.
  • 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: ns01.rocmondriaan.nl, ns02.rocmondriaan.nl.
