Problems

  • ✗
    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: ns.hs-worms.de (143.93.160.9): dial tcp 143.93.160.9:53: i/o timeout; ns.hs-worms.de (2001:4c80:81:a000::9): read tcp [2a01:4f8:1c1c:eebf::1]:45564->[2001:4c80:81:a000::9]:53: i/o timeout.
    #19
  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns-auth.rptu.de: "9.20.29-1~deb13u1-Debian"; ns-sec.hs-worms.de: "9.20.30"; ns.hs-worms.de: "9.20.30". Hide or replace the version string.
    #17
  • !
    Unusual SOA timers
    SOA · retry 2h should be shorter than refresh 1h. Current values: refresh 1h, retry 2h, expire 1000h, negative TTL 1h.
    #23
  • !
    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.

Problems

  • ✗
    No DMARC record
    DMARC · No DMARC record was found for this domain. DMARC is essential for preventing email spoofing. Add a DMARC record with p=reject or at least p=quarantine.
    #5
  • ✗
    No DKIM keys published
    DKIM · _domainkey.hs-worms.de does not exist (NXDOMAIN), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.
    #7
  • !
    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.
