  • ✓ 9 nameservers #6
    Delegated to asia3.akam.net, aus1.akam.net, eur3.akam.net, eur4.akam.net, ns1-102.akam.net, ns1-161.akam.net, usc1.akam.net, use3.akam.net, usw1.akam.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.
  • i
    One address family in one network
    all IPv6 addresses are in 2600:1401:2::/48, while the other address family is spread over several networks.
    #10
  • ✓ 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: asia3.akam.net, aus1.akam.net, eur3.akam.net, eur4.akam.net, usc1.akam.net, use3.akam.net, usw1.akam.net.

    Very low TTLs
    These records have a TTL below 5m, causing extra queries and slower lookups: A (1m), MX (1m39s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 5m; 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.
