DNS data shows some aging or gaps — consider re-scanning for critical decisions

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
MX	`190s`	`1 hour (3600s)`	high	MX TTL is below typical — observed 190s, 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. 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.
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.
NS	`6 hours (21600s)`	`1 day (86400s)`	medium	NS TTL is below typical — observed 6 hours (21600s), typical value is 1 day (86400s). 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 86400 seconds per NIST SP 800-53 SI-18 relevance guidance. Use the TTL Tuner for profile-specific recommendations.
SOA	`28s`	`1 hour (3600s)`	high	SOA TTL is below typical — observed 28s, 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.
CAA	`6 hours (21600s)`	`1 hour (3600s)`	high	CAA TTL is above typical — observed 6 hours (21600s), typical value is 1 hour (3600s). Long TTLs reduce DNS query volume but slow propagation when records change. Consider 3600 seconds for a balance of performance and flexibility per NIST SP 800-53 SI-18 relevance guidance.
A	`5 minutes (300s)`	`1 hour (3600s)`	high	A 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.

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.

Tune TTL for google.com

Reference: NIST SP 800-53 SI-7 (Information Integrity) · RFC 8767 (Serve Stale) · RFC 1035 §3.2.1 (TTL semantics) Note: Some DNS providers (e.g., AWS Route 53 alias records, Cloudflare proxied records) enforce fixed TTLs that cannot be modified. If a finding targets a record you cannot edit, it reflects the observed value rather than a configuration error on your part.

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 1/10 lookups

SPF valid with industry-standard soft fail (~all), 1/10 lookups

v=spf1 include:_spf.google.com ~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 p=reject

DMARC policy reject (100%) - excellent protection

v=DMARC1; p=reject; rua=mailto:mailauth-reports@google.com

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

No forensic reporting (ruf) tag — this is correct. Many tools flag the absence of ruf= as a gap. It is not. 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: CVE-2024-49040 (Exchange sender spoofing), CVE-2024-7208 (multi-tenant DMARC bypass)

DKIM Records RFC 6376 §3.6 Verified

Are outbound emails cryptographically signed? Provider-managed

Provider Verified

DKIM not discoverable via common selectors (large providers use rotating selectors)

Google Workspace detected as primary mail platform — DKIM signing is managed by the provider. The primary provider may use custom selectors not discoverable through standard checks.

Know your DKIM selector? Re-scan with a custom selector to verify.

RFC 6376 (Provider-Managed) — DKIM signing managed by the detected mail provider per RFC 6376.

Known Vulnerabilities: DKIM 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

Can attackers downgrade SMTP to intercept mail? No — TLS enforced

Success ENFORCE Policy Verified

MTA-STS enforced - TLS required for 3 mail server(s)

v=STSv1; id=20210803T010101;

Policy Details:

Mode: enforce
Max Age: 1 days (86400 seconds)
MX Patterns: smtp.google.com, aspmx.l.google.com, *.aspmx.l.google.com

MTA-STS policy enforcement is evaluated in Mail Transport Security below.

TLS-RPT RFC 8460 §3 Verified

Will failures in TLS delivery be reported? Yes — reports configured

Success

TLS-RPT configured - receiving TLS delivery reports

v=TLSRPTv1;rua=mailto:sts-reports@google.com

DANE / TLSA Verified Recon Methodology Can mail servers establish identity without a public CA? via MTA-STS (CA)

RFC 7672 §3 RFC 6698 §2 Not Available

DANE not available — Google Workspace does not support inbound DANE/TLSA on its MX infrastructure

DANE not deployable on Google Workspace

Google Workspace supports DANE for outbound mail verification but does not publish TLSA records for its MX hosts.

Recommended alternative: MTA-STS (already configured)

Note: Google Workspace does validate DANE/TLSA when sending mail to DANE-enabled recipients (outbound DANE).

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).

This domain uses MTA-STS — the best available option for Google Workspace. Since Google Workspace does not support inbound DANE, MTA-STS is the strongest transport security this domain can deploy. MTA-STS enforces TLS via HTTPS-based policy, protecting against downgrade attacks (RFC 8461).

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

BIMI BIMI Spec Verified Warning

Is the brand identity verified and displayed in inboxes? No

No BIMI record found

CAA RFC 8659 §4 Verified Success

Does this domain restrict who can issue TLS certificates? Yes

CAA configured - only pki.goog can issue certificates

Authorized CAs: pki.goog

0 issue "pki.goog"

Since September 2025, all public CAs must verify domain control from multiple geographic locations (Multi-Perspective Issuance Corroboration, CA/B Forum Ballot SC-067). CAA records are now checked from multiple network perspectives before certificate issuance.

Vulnerability Disclosure Policy (security.txt) Is there a verified way to report security issues? Yes RFC 9116

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.

Subdomain Discovery RFC 6962 Recon LIVE What subdomains and infrastructure are exposed in certificate logs? 529 subdomains discovered

How did we find these?

1683 unique certificates 529 current 0 expired 42 CNAMEs Source: Certificate Transparency + DNS Intelligence

Subdomains discovered via CT logs (RFC 6962), DNS probing of common service names, and CNAME chain traversal.

Wildcard certificate detected: *.google.com Active 25 certs 1 CA: Google Trust Services

Explicit SANs found on wildcard certificates: These hostnames were specifically listed alongside the wildcard — revealing infrastructure the operator intentionally secured.

*.aistudio.google.com *.appengine.google.com *.cloud.google.com *.crowdsource.google.com *.datacompute.google.com *.gemini.cloud.google.com *.url.google.com android.clients.google.com

DNS probing and CNAME chain traversal were used to discover additional subdomains below.

Analyze Another Domain

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.

Full List

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.

2679ae8880e24b89be6cb55cb2a8eb3d1fcf35bffd54f29b83171f03720bb50051482ef4267dae46d0aa38438f5c7fab4670ae35b6f8e186a695d74f104fc441

Evaluations reference 12 RFCs. Methods are reproducible using the verification commands provided. Results reflect DNS state at 25 Feb 2026, 14:31 UTC.

Download Raw Intelligence Download Checksum (.sha3)

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-google.com.json.sha3 && echo '---' && openssl dgst -sha3-512 dns-intelligence-google.com.json

Python 3 (cross-platform)

python3 -c "import hashlib; print(hashlib.sha3_512(open('dns-intelligence-google.com.json','rb').read()).hexdigest())"

sha3sum (coreutils 9+)

sha3sum -a 512 dns-intelligence-google.com.json

Compare the output against the .sha3 file or the checksum API at /api/analysis/4375/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 google.com. 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.
