Checks

  • ✓ 3 nameservers #6
    Delegated to ns1.mijn.host, ns2.mijn.host, ns3.mijn.host.
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • ✓ No glue needed #8
    All nameservers are outside the zone, so no glue records are needed.
  • ✓ 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 3 IPv4 /24s and 3 IPv6 /48s.
  • ✓ 3 autonomous systems #11
    The nameservers are spread over: AS214673 (mijnhost - mijn.host B.V., NL): 2 addresses; AS3223 (VOXILITY - Voxility LLP, GB): 2 addresses; AS35470 (XL-AS - Signet B.V., NL): 2 addresses.
  • i
    All nameserver names under .host
    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.
