DNS data is mostly current with minor gaps — good intelligence currency
The following DNS record TTLs deviate from recommended values. Incorrect TTLs can cause caching issues, slow propagation, or unnecessary DNS traffic.

|---|---|---|---|---|
| NS | 6 hours (21600s) |
1 day (86400s) |
medium | NS TTL is below — observed 6 hours (21600s), typical value is 1 day (86400s). Consider setting to 86400 seconds per NIST SP 800-53 SI-18 relevance guidance. |

Big Picture Questions
- How often do you actually change this record? If it hasn’t changed in months, a short TTL is generating unnecessary DNS queries without any benefit.
- Are you preparing for a migration or IP change? Short TTLs make sense temporarily — but should be raised back to 1 hour (3600s) once the change is complete.
- Every DNS lookup adds 20–150ms of latency. With a 60s TTL, returning visitors trigger a fresh lookup every minute. With 3600s, they get cached responses for an hour — faster page loads, no extra infrastructure needed.
- Google runs A records at ~30s because they operate a global anycast network and need to steer traffic dynamically. For a typical website without that infrastructure, copying those TTLs increases query volume with zero upside.

Upgrade DMARC to Reject
Your DMARC policy is set to quarantine. Upgrade to p=reject for maximum protection — reject instructs receivers to discard spoofed mail entirely rather than quarantining it.
A reject policy provides the strongest protection against domain spoofing.

Email Security Methodology Can this domain be impersonated by email? Unlikely SPF and DMARC quarantine policy enforced
SPF Record RFC 7208 §4 Verified
Does this domain declare who may send email on its behalf?
Yes
Success
~all
3/10 lookups
SPF valid with industry-standard soft fail (~all), 3/10 lookups
v=spf1 mx include:mxroute.com a:hogwarts.steinr.eu ~all
RFC 7208 Conformant — This SPF record conforms to the syntax and semantics defined in RFC 7208 §4.
RFC Failure Mode: Unlike DMARC (where unknown tags are silently ignored per RFC 7489 §6.3), SPF with unrecognized mechanisms produces a PermError per RFC 7208 §4.6 — the record fails loudly rather than silently.
Related CVEs:
CVE-2024-7208 (multi-tenant domain spoofing),
CVE-2024-7209 (shared SPF exploitation),
CVE-2023-51764 (SMTP smuggling bypasses SPF)
~all is the industry standard.
Google, Apple, and most providers default to soft fail. CISA (BOD 18-01) and RFC 7489 confirm that DMARC policy — not SPF alone — is the primary enforcement control. Using ~all allows DKIM to be evaluated before a DMARC decision is made.
This domain uses ~all + DMARC quarantine — good protection. Moving to p=reject would achieve the strongest stance.
DMARC Policy RFC 7489 §6.3 Verified
Are spoofed emails rejected or quarantined?
Quarantined, not rejected
Success
p=quarantine
DMARC policy quarantine (100%) - good protection
v=DMARC1; p=quarantine; pct=100; rua=mailto:report@steinet.de,mailto:7e7ade86@in.mailhardener.com; ruf=mailto:report@steinet.de,mailto:7e7ade86@in.mailhardener.com; fo=1
Alignment:
SPF relaxed
DKIM relaxed
No np= tag (DMARCbis) — non-existent subdomains inherit p= policy but adding np=reject provides explicit protection against subdomain spoofing
Forensic reporting (ruf) is configured, but most major providers do not send forensic reports.
RFC 7489 §7.3 warns that forensic reports can expose PII (full message headers or bodies). Google, Microsoft, and Yahoo do not honour ruf= requests. The DMARCbis draft (draft-ietf-dmarc-dmarcbis) has formally removed ruf= from the specification. Consider removing this tag to simplify your record.
RFC 7489 §7.3 — Forensic Reports
Advanced cryptographic posture detected.
Domain appears to be in deliberate DMARC deployment phase — quarantine fully enforced with reporting, consider upgrading to reject
RFC 7489 Present — DMARC record published per RFC 7489 §6.3.
Monitoring Posture Note: Quarantine sequesters authentication failures while preserving full DMARC forensic telemetry (RFC 7489 §7). Some organizations maintain quarantine rather than reject as a deliberate monitoring strategy — failed messages are processed and reported but sequestered from the inbox. See NIST SP 800-177 Rev. 1 for enforcement tradeoffs.
DMARCbis (Pending): draft-ietf-dmarc-dmarcbis will elevate DMARC to Standards Track, obsolete RFC 7489, replace
pct= with t= (testing flag), add np= (non-existent subdomain policy), and mandate DNS tree walk for policy discovery instead of the Public Suffix List.Related CVEs:

DMARC External Reporting Authorization RFC 7489 §7.1
Are external report receivers authorized?
Authorization missing
Warning

| External Domain | Authorization | Auth Record |
|---|---|---|
steinet.de |

in.mailhardener.com |
Authorized |
v=DMARC1;
|
External domain steinet.de has not authorized steinr.eu to send DMARC reports (missing steinr.eu._report._dmarc.steinet.de TXT record)
Third-Party Action Required
This authorization record must be created by the external reporting provider, not by you. Per RFC 7489 §7.1, the receiving domain must publish a TXT record to confirm it accepts DMARC reports from your domain.
What to do: Contact your DMARC reporting provider and ask them to publish the authorization TXT record shown above. If you use a managed DMARC service (e.g., Ondmarc, Dmarcian, Valimail), this is typically handled during onboarding — reach out to their support if the record is missing.
Impact if unresolved: Compliant receivers may silently discard aggregate or forensic reports destined for the unauthorized address, reducing your DMARC visibility.
DANE / TLSA Verified Recon Methodology Can mail servers establish identity without a public CA? via MTA-STS (CA)
No DANE/TLSA records found (checked 3 MX hosts)
DANE (RFC 7672) binds TLS certificates to DNSSEC-signed DNS records, protecting email transport against man-in-the-middle attacks and rogue CAs. It is the primary transport security standard — MTA-STS (RFC 8461) was created as the alternative for domains that cannot deploy DNSSEC. Over 1 million domains use DANE globally, including Microsoft Exchange Online, Proton Mail, and Fastmail. Best practice: deploy both for defense in depth.
Email Transport Security
Two mechanisms protect email in transit. DANE is the primary standard; MTA-STS is the alternative for domains that cannot deploy DNSSEC:
- DNSSEC + DANE (RFC 7672) — Cryptographic chain of trust from DNS root to mail server certificate. Eliminates reliance on certificate authorities. No trust-on-first-use weakness. Requires DNSSEC.
- MTA-STS (RFC 8461) — HTTPS-based policy requiring TLS for mail delivery. Works without DNSSEC but relies on CA trust and is vulnerable on first use (§10). Created for domains where “deploying DNSSEC is undesirable or impractical” (§2).
Industry trend: Microsoft Exchange Online enforces inbound DANE with DNSSEC (GA October 2024), and providers like Proton Mail and Fastmail also support DANE. Google Workspace does not support DANE and relies on MTA-STS. Both mechanisms coexist because DANE is backward-compatible — senders skip the check if the domain isn't DNSSEC-signed (RFC 7672 §1.3).
Brand Security Can this brand be convincingly faked? Possible DMARC quarantine flags spoofed mail (RFC 7489 §6.3) and BIMI with VMC provides verified brand identity in inboxes; upgrade to p=reject to block spoofed mail outright; adding CAA records (RFC 8659) would further restrict certificate issuance for lookalike domains

The IETF AI Preferences working group is developing a
Content-Usage: directive for robots.txt that lets site owners declare whether their content may be used for AI training and inference. This is an active draft, not yet a ratified standard.
Example: Add
Content-Usage: ai=no to robots.txt to deny AI training, or Content-Usage: ai=allow to explicitly permit it.
Without this directive, AI crawler behavior depends on individual crawler policies and User-agent rules.

No exposed secrets, API keys, or credentials were detected in publicly accessible page source or scripts.
Sources scanned (1)
- https://steinr.eu/
What type of scan is this?
This is OSINT (Open Source Intelligence) collection — we check the same publicly accessible URLs that any web browser could visit. No authentication is bypassed, no ports are probed, no vulnerabilities are exploited.
Is this a PCI compliance scan? No. PCI DSS requires scans performed by an Approved Scanning Vendor (ASV) certified by the PCI Security Standards Council. DNS Tool is not an ASV. If you need PCI compliance scanning, engage a certified ASV such as Qualys, Tenable, or Trustwave.
Is this a penetration test? No. Penetration testing involves active exploitation attempts against systems with authorization. Our checks are passive observation of publicly accessible resources — the same methodology used by Shodan, Mozilla Observatory, and other OSINT platforms.

When was a record added, removed, or changed — and could that change be the problem?
Confirm Your Email Configuration
This tool analyzes DNS records, but to verify actual email delivery, send a test email to Red Sift Investigate. Their tool shows exactly how your emails arrive, including SPF/DKIM/DMARC pass/fail results in the headers.
DATA FRESHNESS & METHODOLOGY
All security-critical records (SPF, DMARC, DKIM, DANE/TLSA, DNSSEC, MTA-STS, TLS-RPT, BIMI, CAA) are queried live from authoritative nameservers and cross-referenced against 5 independent public DNS resolvers (Cloudflare, Google, Quad9, OpenDNS, DNS4EU) at the time of each analysis. No security verdict uses cached data.
Registrar data (RDAP) is cached for up to 24 hours because domain ownership and registration details change infrequently. Certificate Transparency logs (subdomain discovery via RFC 6962) are cached for 1 hour because CT entries are append-only historical records. Sections using cached data are marked with a CACHED badge; live queries show LIVE.
Intelligence Sources
This analysis used 4 DNS resolvers (consensus), reverse DNS (PTR), Team Cymru (ASN attribution), IANA RDAP (registrar), crt.sh (CT logs), and SMTP probing (transport). All using open-standard protocols.
Verify Report Integrity SHA-3-512 Has this report been altered since generation? Verify below
This cryptographic hash seals the analysis data, domain, timestamp, and tool version into a tamper-evident fingerprint. Any modification to the report data will produce a different hash. This is distinct from the posture hash (used for drift detection) — the integrity hash uniquely identifies this specific report instance.
b354f982e5460ca5bedf7bc3b6b40617eb06d94435257c0e98c868f57443fd3eaf3eaba17d83f63c29b01878f7706d9a98d468e30ad6f119397ce4b9b91f20a9
Evaluations reference 12 RFCs. Methods are reproducible using the verification commands provided. Results reflect DNS state at 24 Feb 2026, 15:10 UTC.
Download the intelligence dump and verify its integrity, like you would a Kali ISO or any critical artifact. The SHA-3-512 checksum covers every byte of the download — deterministic serialization ensures identical hashes across downloads.
After downloading, verify with any of these commands:
Tip: cd ~/Downloads first (or wherever you saved the files).
OpenSSL + Sidecar (macOS, Linux, WSL)
cat dns-intelligence-steinr.eu.json.sha3 && echo '---' && openssl dgst -sha3-512 dns-intelligence-steinr.eu.json
Python 3 (cross-platform)
python3 -c "import hashlib; print(hashlib.sha3_512(open('dns-intelligence-steinr.eu.json','rb').read()).hexdigest())"
sha3sum (coreutils 9+)
sha3sum -a 512 dns-intelligence-steinr.eu.json
Compare the output against the
.sha3 file or the checksum API at /api/analysis/4193/checksum. Hash algorithm: SHA-3-512 (Keccak, NIST FIPS 202).
Every finding in this report is backed by DNS queries you can run yourself. These vetted one-liners reproduce the exact checks used to build this report for steinr.eu. Our analysis adds multi-resolver consensus, RFC-based evaluation, and cross-referencing — but the underlying data is always independently verifiable. We are intelligence analysts, not gatekeepers.
