  • ✓ 6 nameservers #6
    Delegated to a1-16.akam.net, a16-65.akam.net, a22-67.akam.net, a28-66.akam.net, a3-65.akam.net, a5-67.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 6 IPv4 /24s and 6 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS21342 (AKAMAI-ASN2 - Akamai International B.V., NL): 12 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.
    #11
  • 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.

    Software version disclosed
    These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: a1-16.akam.net: "41824.11"; a1-16.akam.net: "41824.6"; a16-65.akam.net: "48878.29"; a16-65.akam.net: "48878.32"; a22-67.akam.net: "48878.26"; a22-67.akam.net: "48878.33"; a28-66.akam.net: "48878.26"; a28-66.akam.net: "48878.32"; a3-65.akam.net: "41824.5"; a3-65.akam.net: "41824.8"; a5-67.akam.net: "41824.8"; a5-67.akam.net: "41824.7".

  • ✓ Zone transfers refused #18
    No nameserver allows a zone transfer to the public.
  • ✓ TCP supported #19
    All nameservers answer over TCP.
  • ✓ EDNS supported #20
    All nameservers support EDNS(0).

    NSEC3 with extra iterations or salt
    NSEC3 uses 10 iterations and a 10-byte salt. RFC 9276 recommends 0 iterations and no salt: extra iterations cost resolvers CPU and add no real protection, and some validators treat high counts as insecure.
