Problems

  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.kgrz-ks.de: "PowerDNS Authoritative Server 4.8.0"; ns2.ekom21.de: "PowerDNS Authoritative Server 4.8.0"; ns3.ekom21.de: "PowerDNS Authoritative Server 4.8.0"; ns4.ekom21.de: "PowerDNS Authoritative Server 4.8.0"; pdns.kiv-host.de: "PowerDNS Authoritative Server 4.8.0". Hide or replace the version string.

  • !
    NSEC3 with extra iterations or salt
    DNSSEC · NSEC3 uses 10 iterations and a 5-byte salt. RFC 9276 recommends 0 iterations and no salt: extra iterations cost resolvers CPU and add no real protection, and some validators treat high counts as insecure.

    Policy: quarantine

    No key under common selectors
    DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.
