  • ✓ 8 nameservers #6
    Delegated to asia3.akam.net, eur2.akam.net, eur5.akam.net, ns1-105.akam.net, ns1-8.akam.net, usc4.akam.net, use4.akam.net, usw4.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.
  • ✓ 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): 1 address; 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
  • i
    Partly IPv6
    These nameservers have no IPv6 address: asia3.akam.net, eur2.akam.net, eur5.akam.net, usc4.akam.net, use4.akam.net.
