    #7
  • ✓ 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): 1 address; 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: eur1.akam.net, eur3.akam.net, eur4.akam.net, usc1.akam.net, usc2.akam.net, use4.akam.net.

    Very low TTLs
    These records have a TTL below 5m, causing extra queries and slower lookups: A (20s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 6h; resolvers may use either.
