  • ✓ 8 nameservers #6
    Delegated to ns21.cloudns.net, ns22.cloudns.net, ns23.cloudns.net, ns24.cloudns.net, pns21.cloudns.net, pns22.cloudns.net, pns23.cloudns.net, pns24.cloudns.net.
  • ✓ 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 8 IPv4 /24s and 5 IPv6 /48s.
  • ✓ 5 autonomous systems #11
    The nameservers are spread over: AS203391 (CLOUDNSNET - Cloud DNS Ltd, BG): 8 addresses; AS205787 (Publicloud - Public Cloud Ltd., BG): 2 addresses; AS213230 (HETZNER-CLOUD2-AS - Hetzner Online GmbH, DE): 2 addresses; AS35661 (VIRTUASYS-EU - VIRTUA SYSTEMS SAS, FR): 2 addresses; AS43350 (NFORCE - NForce Entertainment B.V., NL): 2 addresses.
  • i
    All nameserver names under .net
    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.
