• ✓ 4 nameservers #6

  Delegated to dns1.novagraaf-dns.com, dns2.novagraaf-dns.net, dns3.novagraaf-dns.nl, dns4.novagraaf-dns.eu.
• ✓ 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 2 IPv4 /24s and 2 IPv6 /48s.
• i

  All nameservers in one AS

  All nameserver addresses are announced by one network operator (AS62597 (NSONE - NSONE Inc, US): 8 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.

  #11
• ✓ Nameserver names under 4 TLDs #12

  Nameserver names use the TLDs .com, .eu, .net, .nl.
• ✓ All reachable over IPv6 #13

  Every nameserver has an IPv6 address.
