  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: a1-249.akam.net: "41824.4"; a1-249.akam.net: "41824.5"; a12-65.akam.net: "48878.26"; a12-65.akam.net: "48878.32"; a16-64.akam.net: "48878.27"; a16-64.akam.net: "48878.29"; a3-67.akam.net: "41824.11"; a3-67.akam.net: "41824.9"; a4-64.akam.net: "48878.32"; a4-64.akam.net: "48878.26"; a7-65.akam.net: "41824.6". 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 2d and in the zone 1d; resolvers may use either.

Problems

  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    Not configured
    TLS · MTA-STS is not configured, so other mail servers fall back to unencrypted delivery when TLS fails or is stripped by an attacker. Publish a _mta-sts TXT record and a policy at https://mta-sts.<domain>/.well-known/mta-sts.txt.
