  • ✓ 6 nameservers #6

  • ✓ 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 6 IPv4 /24s and 6 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS20940 (AKAMAI-ASN1 - Akamai International B.V., NL): 2 addresses; AS21342 (AKAMAI-ASN2 - Akamai International B.V., NL): 10 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.

    Hidden master
    The primary nameserver dns1.p05.nsone.net is not listed as a nameserver: a hidden master that only feeds the public secondaries. That is a common setup; make sure it is not reachable for zone transfers from outside.

    Very low TTLs
    These records have a TTL below 5m, causing extra queries and slower lookups: A (20s), MX (1m), NS (1m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 1m; resolvers may use either.

    No CAA records
    Without CAA records any certificate authority may issue certificates for this domain. A CAA record limits issuance to the CAs you use.
