The following DNS record TTLs deviate from recommended values. Incorrect TTLs can cause caching issues, slow propagation, or unnecessary DNS traffic.
| Record Type | Observed TTL | Typical TTL | Severity | Context |
|---|---|---|---|---|
| TXT | 5 minutes (300s) |
1 hour (3600s) |
high | TXT TTL is below typical — observed 5 minutes (300s), typical value is 1 hour (3600s). Short TTLs increase DNS query volume but enable faster propagation. If you are preparing for a migration or need rapid failover, this may be intentional (RFC 1035 §3.2.1). For steady-state production, consider 3600 seconds per NIST SP 800-53 SI-18 relevance guidance. Use the TTL Tuner for profile-specific recommendations. |
| AAAA | 5 minutes (300s) |
1 hour (3600s) |
high |
AAAA TTL is below typical — observed 5 minutes (300s), typical value is 1 hour (3600s). Short TTLs increase DNS query volume but enable faster propagation.

Use the TTL Tuner for profile-specific recommendations.
Provider Note: This TTL (5 minutes (300s)) matches Cloudflare's fixed proxied-record TTL. If this record is proxied (orange cloud), the TTL is enforced by Cloudflare and cannot be changed. Disable proxying (gray cloud) to regain TTL control, at the cost of losing Cloudflare's DDoS protection and CDN.

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.

| Minimum (Neg. Cache) | 1800s | 300–86,400s (5 min – 1 day) |
Expire: SOA Expire is 7 days (604800s). RFC 1912 §2.2 recommends 1,209,600–2,419,200 seconds (14–28 days). If the primary nameserver becomes unreachable, secondary nameservers will stop serving this zone after only 7 days (604800s). Cloudflare's anycast architecture reduces the practical risk, but this value departs from the RFC recommendation.
Independent RFC compliance assessment for Cloudflare. Each finding cites the specific RFC section and reports what the engineering community consensus is. We report honestly — if a provider deviates from standards, we explain what they did differently and what the RFCs actually say.
SOA Expire below RFC 1912 recommendation
RFC 1912 §2.2
Cloudflare sets SOA Expire to 604,800 seconds (7 days). RFC 1912 §2.2 recommends 1,209,600–2,419,200 seconds (14–28 days). This means secondary nameservers stop serving the zone sooner if the primary becomes unreachable. Cloudflare's position is that their anycast architecture makes traditional zone transfer semantics less relevant. SOA timers are not editable on Free, Pro, or Business plans.
Below RFC recommendation
Proxied record TTLs fixed at 300s
RFC 2181 §5.2
Cloudflare overrides the zone administrator's TTL to 300 seconds for all proxied (orange-cloud) records. RFC 2181 §5.2 requires TTL uniformity within an RRset but does not mandate a specific value. As the authoritative server, Cloudflare is technically within its rights, but the administrator loses TTL control. This can affect ACME DNS-01 challenges and automation workflows that depend on rapid propagation.
Technically compliant, but overrides administrator intent
Non-standard SOA serial format
RFC 1912 §2.2
RFC 1912 recommends YYYYMMDDNN format for SOA serial numbers (e.g., 2026022501). Cloudflare uses a proprietary serial number format that does not encode the date. RFC 1035 only requires the serial to increment on changes, so this is compliant with the mandatory standard but breaks the convention relied on by monitoring tools.
Compliant with RFC 1035, deviates from RFC 1912 convention
Negative cache TTL delays new records
RFC 2308 §5
Cloudflare's SOA MINIMUM (negative cache TTL) is 1,800–3,600 seconds (30–60 minutes). This controls how long resolvers cache NXDOMAIN responses. Newly created DNS records — including ACME DNS-01 challenge TXT records for Let's Encrypt — may be invisible for up to 1 hour even after creation. This causes certificate issuance failures for automation tools like cert-manager and Traefik. Workaround: pre-create placeholder records before they're needed. This is RFC-compliant but aggressive compared to the 300–900 seconds common at other providers.
RFC-compliant, but causes real-world automation failures
Historical RFC 2181 §5.2 violation: TTL mismatch in CNAME RRsets
RFC 2181 §5.2
In February 2022, Cloudflare's resolver (1.1.1.1) returned CNAME responses with mismatched TTLs within the same RRset — including cases where one TTL was zero and another was non-zero. RFC 2181 §5.2 explicitly states: 'the TTLs of all RRs in an RRSet must be the same.' systemd-resolved (used by Arch Linux, Ubuntu, Fedora, and most modern Linux distributions) correctly rejected these responses per the RFC, causing widespread DNS resolution failures. Cloudflare acknowledged the issue and it appears to have been fixed, but it demonstrated that Cloudflare's DNS infrastructure can deviate from RFC requirements in ways that break compliant resolver implementations.

Email Security Methodology Can this domain be impersonated by email? No SPF and DMARC reject policy enforced
SPF Record RFC 7208 §4 Verified
Does this domain declare who may send email on its behalf?
Yes
Success
~all
2/10 lookups
SPF valid with industry-standard soft fail (~all), 2/10 lookups
v=spf1 include:_spf.protonmail.ch mx ~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 reject: the strongest compatible security stance, aligned with CISA and RFC guidance.
DMARC Policy RFC 7489 §6.3 Verified
Are spoofed emails rejected or quarantined?
Yes — reject policy
Success

Alignment:

DKIM strict
No np= tag (DMARCbis) — non-existent subdomains inherit p= policy but adding np=reject provides explicit protection against subdomain spoofing
No forensic reporting (ruf) tag — this is correct.
The absence of ruf= is not a gap. 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 regardless. The DMARCbis draft (draft-ietf-dmarc-dmarcbis) has formally removed ruf= from the specification, confirming its deprecation. Omitting ruf= is the recommended modern practice.
RFC 7489 §7.3 — Forensic Reports
RFC 7489 Conformant — DMARC record conforms to RFC 7489 §6.3 with full enforcement.
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:

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 reject policy blocks email spoofing (RFC 7489 §6.3) and CAA restricts certificate issuance (RFC 8659 §4), but no BIMI brand verification — lookalike domains display identically in inboxes without visual proof of authenticity

Public Exposure Checks Are sensitive files or secrets exposed? No
No exposed secrets detected in public page source — same-origin, non-intrusive scan of publicly visible page source and scripts.
No exposed secrets, API keys, or credentials were detected in publicly accessible page source or scripts.
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.

Domain Security Methodology Can DNS responses be tampered with in transit? Possible DNSSEC is not deployed, DNS responses are not cryptographically verified
DNSSEC RFC 4033 §2 Verified Unsigned
DNSSEC not configured - DNS responses are unsigned
Enterprise DNS Context: DNSSEC is the only standardized, DNS-verifiable mechanism that cryptographically authenticates responses between authoritative servers and resolvers (RFC 4033 §2, RFC 4035). Without it, DNS responses are technically vulnerable to in-transit tampering. Enterprise operators may employ compensating controls (anycast, DDoS mitigation, private peering, TSIG) — however, these do not provide DNS-layer data authentication to third-party resolvers and are not verifiable via DNS alone.
Visibility: DNS-only — network-layer compensating controls cannot be observed or verified through DNS queries. This assessment reflects what is provable from the DNS evidence available.

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.
0e5fe83d228b1fb5c57f5b82a0d76d8a35c863162113e3ff817e074c108c979d0b956d7dc0f5e84a3c96160811056172c042d20c3bb4d074bc7e67a95f9cf9b0
Evaluations reference 12 RFCs. Methods are reproducible using the verification commands provided. Results reflect DNS state at 2 Mar 2026, 01:45 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-hirt.dev.json.sha3 && echo '---' && openssl dgst -sha3-512 dns-intelligence-hirt.dev.json
Python 3 (cross-platform)
python3 -c "import hashlib; print(hashlib.sha3_512(open('dns-intelligence-hirt.dev.json','rb').read()).hexdigest())"
sha3sum (coreutils 9+)
sha3sum -a 512 dns-intelligence-hirt.dev.json
Compare the output against the
.sha3 file or the checksum API at /api/analysis/5211/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 hirt.dev. 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.
