Priority Actions 4 total Achievable posture: Low Risk
High Add DMARC Reject for No-Mail Domain

This domain has no MX records and appears to be a website-only domain. A DMARC reject policy tells receiving mail servers to reject any email claiming to be from your domain.

RFC 7489
High Lock Down SPF for No-Mail Domain

This domain has no MX records and appears to be a website-only domain. Publishing a strict SPF record explicitly declares that no servers are authorized to send email, preventing attackers from spoofing your domain.

RFC 7208
Medium Enable DNSSEC

DNSSEC is not enabled for this domain. DNSSEC provides cryptographic authentication of DNS responses, preventing cache poisoning and DNS spoofing attacks.

Email Security Methodology Can this domain be impersonated by email? Yes no SPF or DMARC protection

SPF Record RFC 7208 §4 Gold

Does this domain declare who may send email on its behalf? No
Warning

No SPF record found

RFC Stance: RFC 7208 defines the SPF mechanism for domains that choose to publish sender authorization. The standard does not mandate SPF publication — it is a voluntary security control.
Operational Security: We flag its absence because any server on the internet can send email claiming to be this domain. Attackers send from a domain — they do not need the domain to have email infrastructure.
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)

DMARC Policy RFC 7489 §6.3 Gold

Are spoofed emails rejected or quarantined? No policy published
Warning

No DMARC record found

RFC Stance: RFC 7489 is classified as Informational (not Standards Track). DMARC is a widely adopted industry practice but is not an IETF-mandated standard.
Operational Security: Without DMARC, receiving mail servers have no policy for handling SPF/DKIM failures. Spoofed messages may be delivered to recipients.
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 Gold

Are outbound emails cryptographically signed? Not discoverable
Not Discoverable

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

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 Gold

Can attackers downgrade SMTP to intercept mail? Not prevented
Warning

No MTA-STS record found

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

TLS-RPT RFC 8460 §3 Gold

Will failures in TLS delivery be reported? No reporting
Warning

No TLS-RPT record found

02 Chain of authority · L1 Domain Security Can DNS answers and certificate issuance be trusted? DANE / TLSA CAA Delegation DNSSEC Operations DNSSEC & NS Partially Signed
DANE / TLSA Gold Recon Methodology Can mail servers establish identity without a public CA? No
RFC 7672 §3 RFC 6698 §2 Not Configured

No MX records available — DANE check skipped

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).
This domain has neither DANE nor MTA-STS. Mail transport relies on opportunistic TLS without policy enforcement, leaving it vulnerable to downgrade attacks. Deploy DANE (RFC 7672) with DNSSEC for the strongest protection, or MTA-STS (RFC 8461) if DNSSEC is not feasible.

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).

CAA RFC 8659 §4 Gold Warning

Does this domain restrict who can issue TLS certificates? No

No CAA records found - any CA can issue certificates

Policy Assessment Primary

No transport enforcement policies detected. Mail delivery relies on opportunistic STARTTLS, which is vulnerable to downgrade attacks (RFC 3207). Consider deploying MTA-STS (RFC 8461) or DANE (RFC 7672).

Telemetry
TLS-RPT not configured — domain has no visibility into TLS delivery failures from real senders
Live Probe Supplementary
Skipped — No MX records found for this domain
What Is Measured: Our probe’s TLS 1.3 handshake offers the hybrid post-quantum group X25519MLKEM768 (X25519 combined with ML-KEM-768). The Key Exchange column reports the group each mail server actually negotiated — direct, observed evidence of its post-quantum readiness toward a hybrid-capable client.
Quantum-Safe Hybrid: The session key agreement combines classical X25519 with ML-KEM-768, standardized in FIPS 203 (final, August 2024). This protects the key exchange against “harvest now, decrypt later” collection by a future quantum adversary.
Classical: The server completed the handshake without selecting the offered hybrid group. This is not a deviation — no RFC currently requires post-quantum key exchange. The X25519MLKEM768 group is defined in draft-ietf-tls-ecdhe-mlkem (Standards Track draft, not yet an RFC); the hybrid approach is described in draft-ietf-tls-hybrid-design (IESG-approved Informational). Servers supporting only other hybrid groups also read as Classical here.
Transition Outlook: NIST’s draft transition guidance (NIST IR 8547) projects quantum-vulnerable algorithms being deprecated after 2030 and disallowed after 2035. Hybrid key exchange requires TLS 1.3. This finding is informational and does not affect this domain’s grade.

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.

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
SOA 1108s 1 hour (3600s) medium SOA TTL is below typical — observed 1108s, 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-7 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 (1108s) is set by Cloudflare, not the zone administrator. See RFC 1912 §2.2 for recommended SOA timer values.
A 290s 1 hour (3600s) high A TTL is below typical — observed 290s, 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-7 relevance guidance. Use the TTL Tuner for profile-specific recommendations.
NS 20908s 1 day (86400s) medium NS TTL is below typical — observed 20908s, 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-7 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.

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.

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.
