  • ✓ 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 7 IPv4 /24s and 2 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): 9 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
  • i
    Partly IPv6
    These nameservers have no IPv6 address: eur2.akam.net, eur5.akam.net, eur6.akam.net, usc2.akam.net, use2.akam.net.

    Very low TTLs
    These records have a TTL below 5m, causing extra queries and slower lookups: A (20s), AAAA (20s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 15m; resolvers may use either.

  • ✓ No CNAME at the apex #33
    The zone apex has no CNAME record.

    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.
