Problems

  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.avm.de: "9.18.39-0ubuntu0.22.04.7-Ubuntu"; ns2.avm.de: "9.18.39-0ubuntu0.22.04.7-Ubuntu"; ns3.avm.de: "9.18.39-0ubuntu0.22.04.7-Ubuntu". Hide or replace the version string.

    Not signed
