  • ✓ 6 nameservers #6
    Delegated to ns0034.secondary.cloudflare.com, ns0139.secondary.cloudflare.com, ns0140.netapp.com, ns030.netapp.com, ns060.netapp.com, ns100.netapp.com.
  • ✓ 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: ns0140.netapp.com, ns030.netapp.com, ns060.netapp.com, ns100.netapp.com.
  • ✓ 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 6 IPv4 /24s and 4 IPv6 /48s.
  • ✓ 4 autonomous systems #11
    The nameservers are spread over: AS13335 (CLOUDFLARENET - Cloudflare, Inc., US): 4 addresses; AS16509 (AMAZON-02 - Amazon.com, Inc., US): 1 address; AS17394 (NETAPP-AS-1 - NetApp, Inc., US): 4 addresses; AS24477 (NETAPPAS - NetApp, Inc., JP): 1 address.
  • i
    All nameserver names under .com
    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: ns030.netapp.com, ns100.netapp.com.
