    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: a24-67.akam.net, a3-67.akam.net. a1-248.akam.net, a11-66.akam.net, a16-65.akam.net, a2-64.akam.net, a24-67.akam.net, a3-67.akam.net report NS a1-248.akam.net a11-66.akam.net a16-65.akam.net a2-64.akam.net a24-67.akam.net a3-67.akam.net.

    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: a1-248.akam.net: "41824.4"; a1-248.akam.net: "41824.5"; a11-66.akam.net: "41824.11"; a16-65.akam.net: "48878.31"; a2-64.akam.net: "48878.29"; a2-64.akam.net: "48878.26"; a24-67.akam.net: "48878.29"; a24-67.akam.net: "48878.31"; a3-67.akam.net: "41824.7". Hide or replace the version string.

    Not signed
    DNSSEC · The zone is not signed with DNSSEC, so answers can be spoofed. Enable DNSSEC at your DNS provider and publish the DS record at your registrar.
    #27
  • !
    Very low TTLs
    Records · 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 1d and in the zone 15m; resolvers may use either.
