    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns3.uni-koblenz.de: "9.18.39-0ubuntu0.24.04.8-Ubuntu"; ns4.uni-koblenz.de: "9.18.39-0ubuntu0.24.04.8-Ubuntu". 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.
