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 217s 1 hour (3600s) high MX TTL is below typical — observed 217s, 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 21570s 1 day (86400s) medium NS TTL is below typical — observed 21570s, 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 1770s 1 hour (3600s) medium SOA TTL is below typical — observed 1770s, 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.
Provider Note: Cloudflare manages SOA timers automatically. Free/Pro/Business plans cannot modify SOA values. Observed TTL (1770s) is set by Cloudflare, not the zone administrator. See RFC 1912 §2.2 for recommended SOA timer values.
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.
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.
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.

TXT 270s 1 hour (3600s) high TXT TTL is below typical — observed 270s, 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.

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.

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.
RFC 1912 §2.2

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.

Was a documented RFC violation — appears resolved
This assessment is based on RFC specifications, provider documentation, and documented incidents from DNS engineering communities. DNS Tool does not have a commercial relationship with any provider listed.

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 5/10 lookups

SPF valid with strict enforcement (-all), 5/10 lookups

v=spf1 a mx ip4:216.144.250.150 include:_spf.google.com include:amazonses.com include:sendgrid.net -all
RFC 7489: -all may cause rejection before DMARC evaluation, preventing DKIM from being checked
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)
SPF hard fail (-all): compliance-strong, but can short-circuit DMARC. RFC 7489 notes that -all can cause some receivers to reject mail during the SMTP transaction — before DKIM is checked and before DMARC can evaluate the result. A message that would pass DMARC via DKIM alignment may be rejected prematurely. For most domains, ~all + DMARC p=reject is the strongest compatible posture — it allows every authentication method (SPF, DKIM, DMARC) to be fully evaluated before a decision is made.
DMARC enforcement is partial (quarantine). -all may preempt DKIM/DMARC evaluation at some receivers. Consider p=reject for full enforcement; ~all is more DMARC-compatible.

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; rua=mailto:286ba4a9ebbb464db5e05f8972652e84@dmarc-reports.cloudflare.net
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. 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
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.

DANE / TLSA Verified Recon Methodology Can mail servers establish identity without a public CA? No
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

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 has neither DANE nor MTA-STS. Since Google Workspace does not support inbound DANE, deploy MTA-STS (RFC 8461) to enforce TLS and protect against downgrade attacks.

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 DMARC quarantine flags but does not reject spoofed mail (RFC 7489 §6.3), and no BIMI brand verification — lookalike domains display identically in inboxes; CAA restricts certificate issuance (RFC 8659 §4) but visual brand faking remains open

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 Let's Encrypt, ssl.com, cansignhttpexchanges=yes, Sectigo, DigiCert can issue certificates (wildcard issuance: ssl.com, Let's Encrypt, cansignhttpexchanges=yes, DigiCert, Sectigo per RFC 8659 §4.3)

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.

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.

8d23fa96706f0496fc4db6666d3e9904944f42275923931e92ee7235c408b9ead6e300fdef31466b842c46c33efc39f97be0312df976d8041df9532cabe4b0bb
Evaluations reference 12 RFCs. Methods are reproducible using the verification commands provided. Results reflect DNS state at 8 Mar 2026, 14:14 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-uptimerobot.com.json.sha3 && echo '---' && openssl dgst -sha3-512 dns-intelligence-uptimerobot.com.json
Python 3 (cross-platform) 
python3 -c "import hashlib; print(hashlib.sha3_512(open('dns-intelligence-uptimerobot.com.json','rb').read()).hexdigest())"
sha3sum (coreutils 9+) 
sha3sum -a 512 dns-intelligence-uptimerobot.com.json
Compare the output against the .sha3 file or the checksum API at /api/analysis/6606/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 uptimerobot.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.
