Engineer's DNS Intelligence Report
| Parameter | Current | Suggested | Severity | Rationale |
|---|---|---|---|---|
| timeout_seconds | 5s |
8s |
low | Average scan duration is 39.2s, suggesting DNS responses are slow for this domain. Increasing timeout from 5s to 8s prevents premature resolution failures. RFC 8767 |
Email Security Methodology Can this domain be impersonated by email? Uncertain incomplete configuration
SPF Record RFC 7208 §4 Verified
SPF valid with industry-standard soft fail (~all), 1/10 lookups
DMARC Policy RFC 7489 §6.3 Verified
No DMARC record found
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.DKIM Records RFC 6376 §3.6 Verified
Found DKIM records for 1 selector(s)
l= tag body length vulnerability (attacker appends unsigned content to signed mail),
weak key exploitation (keys below 1024-bit are cryptographically breakable per RFC 6376 §3.3.3),
DKIM replay attacks (re-sending legitimately signed messages at scale)
MTA-STS RFC 8461 §3 Verified
No MTA-STS record found
MTA-STS policy enforcement is evaluated in Mail Transport Security below.
TLS-RPT RFC 8460 §3 Verified
No TLS-RPT record found
DANE / TLSA Verified Recon Methodology Can mail servers establish identity without a public CA? No
No DANE/TLSA records found (checked 1 MX host)
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? Likely
BIMI BIMI Spec Verified Warning
No BIMI record found
CAA RFC 8659 §4 Verified Warning
No CAA records found - any CA can issue certificates
Vulnerability Disclosure Policy (security.txt) Is there a verified way to report security issues? No RFC 9116
No security.txt found
/.well-known/security.txt provides security researchers with a standardized way to report vulnerabilities.
See securitytxt.org for a generator.
AI Surface Scanner Beta Is this domain discoverable by AI — and protected from abuse? No
No AI governance measures detected
llms.txt llmstxt.org
AI Crawler Governance (robots.txt) RFC 9309 IETF Draft
Content-Usage Directive IETF Draft
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.
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.

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.

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).
cat dns-intelligence-spitalgiurgiu.ro.json.sha3 && echo '---' && openssl dgst -sha3-512 dns-intelligence-spitalgiurgiu.ro.json
python3 -c "import hashlib; print(hashlib.sha3_512(open('dns-intelligence-spitalgiurgiu.ro.json','rb').read()).hexdigest())"
sha3sum -a 512 dns-intelligence-spitalgiurgiu.ro.json

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 spitalgiurgiu.ro. 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.
