FIX
IPv6 records exist but unreachable
Warning::
IPv6 DNS records exist but server is not reachable
Having AAAA records but an unreachable server is worse than no AAAA — clients may experience delays before falling back to IPv4.
Got: 2606:4700:3033::ac43:a4d6, 2606:4700:3035::6815:af7
Info::
IPv6 connection error
Got: dial tcp6 [2606:4700:3033::ac43:a4d6]:443: connect: network is unreachable
IPv6 Misconfigured
AAAA Records 2606:4700:3033::ac43:a4d6, 2606:4700:3035::6815:af7 Connection UNREACHABLE

Having AAAA records but an unreachable server is worse than no AAAA — clients may experience delays before falling back to IPv4.

Why this matters

Advertising IPv6 (AAAA records) without a reachable server means IPv6-preferring clients silently fail every connection.

Learn more ▾

Modern browsers prefer IPv6 if AAAA exists (Happy Eyeballs algorithm). If the IPv6 server isn't reachable, browsers fall back to IPv4 — but with seconds of added latency per request. Either fix IPv6 reachability or remove the AAAA records.

B
DNSSEC
Unsigned (DNSSEC not deployed)
REVIEW
Unsigned (DNSSEC not deployed)
Info::
DNSSEC is not deployed
The zone is not DNSSEC-signed. Users on validating resolvers (Cloudflare 1.1.1.1, Quad9 9.9.9.9, growing default in mobile resolvers) get no protection against DNS spoofing for this domain. Most registrars now offer DNSSEC at a single click; consider enabling it for sites where authenticity matters (banking, healthcare, government).
B
CAA Records
No CAA records (any CA may issue certificates)
REVIEW
No CAA records (any CA may issue certificates)
Info::
No CAA records published
Without CAA records, any publicly-trusted CA can issue certificates for this domain. Adding a CAA record (`yourdomain. IN CAA 0 issue "letsencrypt.org"`) restricts issuance to CAs you authorize. Required by CAB Forum baseline since 2017; the default of 'any CA' is widely supported but is the broader attack surface for issuance fraud.

This domain expires on August 30, 2026. Domains that expire accidentally cause complete website downtime. Enable auto-renewal or renew manually now.

Why this matters

DNSSEC protects against DNS spoofing attacks. While not required, enabling DNSSEC adds an additional layer of security. Contact your DNS provider to enable it.

Why this matters

Without DNSSEC, an attacker who can poison your DNS can hijack your domain — and SSL certs alone don't stop them.

Learn more ▾

DNSSEC adds cryptographic signatures to DNS records, preventing forged responses from poisoning resolver caches. Without it, an attacker who controls the network path can redirect your domain to a malicious server before any HTTPS handshake happens. Most modern registrars (Cloudflare, Google Domains, Route 53) enable it with one toggle.

Source: ICANN / RFC 4033

The domain can be transferred without an unlock step. Enable registrar lock (clientTransferProhibited) in your registrar's control panel to protect against unauthorized or accidental transfers.

Why this matters

Without registrar lock, an attacker who phishes your registrar credentials can transfer the domain in minutes — total brand hijack.

Learn more ▾

Registrar lock (clientTransferProhibited, clientUpdateProhibited, clientDeleteProhibited) requires extra verification before any transfer/update/delete. Every major registrar offers it free. Combined with 2FA on your registrar account, it's the strongest defense against domain hijacking.

Recommended actions

  • Extend HSTS max-age to at least 31536000 (1 year) to meet the preload list criteria
  • Add includeSubDomains to the HSTS directive
  • Add the preload directive and submit to hstspreload.org once max-age + includeSubDomains are in place
  • Enable DNSSEC on your domain for DNS spoofing protection
  • Enable OCSP stapling on your TLS server to remove a CA roundtrip and protect user privacy

No status page link detected
Info::
No operational status page link detected
Status pages communicate planned maintenance and incidents to users -- a hallmark of operationally-mature services. Most SaaS teams publish one via Atlassian Statuspage, Instatus, BetterUptime, or a self-hosted Cachet. Smaller sites legitimately don't need one; flagged as Info, not a failure.

SPF helps prevent email spoofing. Add a TXT record starting with 'v=spf1'.

Why this matters

Without SPF, receiving servers can't validate sending IPs — your domain is easier to spoof in phishing.

Learn more ▾

SPF complements DMARC. Both should be published. SPF records list authorized sending IPs (e.g., `v=spf1 include:_spf.google.com ~all` for Google Workspace). After publishing, verify in Google Postmaster Tools or mxtoolbox.

    <p>PearReview ist ein Assistent zum Planen und Durchführen  von Reviews. Unter einem Review wird hier speziell das technische Review im  Software-Bereich (*) verstanden. PearReview lässt sich allerdings problemlos  auch in anderen Bereichen einsetzten.</p>
<p>PearRview ist eine Open Source Software, die im Rahmen  des Software-Praktikums an der Universität Stuttgart entstanden ist und kann  kostenlos im privaten und kommerziellen Gebrauch  eingesetzt werden.</p>
<p>PearReview unterstützt das Planen von Review-Sitzungen,  erlaubt es den Teilnehmern bestimmte Rollen (Moderator, Notar, Gutachter, Autor  und Kunde) zu zuweisen und schriftliche Einladungen in Form von PDF-Dokumenten  für sie zu erstellen.<br/>
  Es ist möglich den Gutachtern bestimmte Aspekte zu  zuweisen, auf die sie den Prüfling untersuchen können. Aspekte können in  XML-Form als Kataloge verwaltet und dadurch in mehreren Projekten verwendet  werden.<br/>
  Während der Review-Sitzung können Befunde mit PearReview  in einem Protokoll notiert, verwaltet und exportiert werden. </p>
<p>  <u>Nachtrag:</u> Das Projekt wurde gestern (24.07.2024) abgeschlossen und uns drängte sich die Frage auf, welche Zukunft PearReview einschlagen sollte. Daher haben wir (die Entwickler) einen einfachen Plan aus 2 Schritten ausgearbeitet, der das weitere Vorgehen bestimmen wird: </p>
<ul>
<li>Schritt 1 - Wartung und Verbreitung
<ul>
<li>Korrektur bestehender Fehler</li>
<li>Verbesserung einiger Usability-Macken</li>
<li>Verbreitung von PearReview</li>
</ul>
</li>
<li>Schritt 2 - Erweiterung
<ul>
<li>Sammeln guter Ideen</li>
<li>Erweiterung der Funktionen</li>
</ul>
</li>
</ul>
<p>
  Es ist daher auch eine neue Website in Planung, die die neuen Anforderungen (Bugtracking usw.) erfüllen kann. Unser Plakat aus der gestrigen Präsentation steht ebenfalls zum <a href="PearReview-Plakat.pdf">Download</a> bereit. Wir würden uns über <a href="kontakt">Feedback</a> sehr freuen.</p>
<p></p>
<p>* PearReview unterstützt die Vorgehensweise, die in  &quot;Ludewig, J. and Lichter, H. (2008): Software Engineering. dpunkt.verlag  GmbH, ISBN 3-89864-268-2&quot;  beschrieben wird. Weiterführende Links zu Reviews:</p>
