    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: gaia.bitwizard.nl; only in the zone: ns2.bitwizard.nl. gaia.bitwizard.nl, ns.bitwizard.nl, ns2.binele.nl, ns2.bitwizard.nl report NS ns.bitwizard.nl ns2.binele.nl ns2.bitwizard.nl.

  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: gaia.bitwizard.nl, ns.bitwizard.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 2 IPv4 /24s and 1 IPv6 /48.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS20857 (TRANSIP-AS - Signet B.V., NL): 2 addresses; AS49127 (ASIMO-AS - Asimo Networks B.V., NL): 3 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: gaia.bitwizard.nl, ns.bitwizard.nl, ns2.bitwizard.nl.
