Problems

  • ✗
    Lame delegation
    Nameservers · These nameservers don't answer authoritatively for the zone, so resolvers ignore them: nsjc8hos01.telefonica-data.com (213.0.43.37): REFUSED, authoritative=false.
    #15
  • ✗
    No DNS over TCP
    Nameservers · DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: nsjc8hos01.telefonica-data.com (213.0.43.37): .

    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: nsjc8hos01.telefonica-data.com. a1-86.akam.net, a12-65.akam.net, a2-66.akam.net, a26-67.akam.net, a3-64.akam.net, a7-65.akam.net report NS a1-86.akam.net a12-65.akam.net a2-66.akam.net a26-67.akam.net a3-64.akam.net a7-65.akam.net.

    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: a1-86.akam.net: "41824.9"; a1-86.akam.net: "41824.10"; a12-65.akam.net: "48878.33"; a12-65.akam.net: "48878.27"; a2-66.akam.net: "48878.33"; a2-66.akam.net: "48878.32"; a26-67.akam.net: "48878.31"; a26-67.akam.net: "48878.29"; a3-64.akam.net: "41824.10"; a7-65.akam.net: "41824.6"; a7-65.akam.net: "41824.11". 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). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 2d; resolvers may use either.
