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 | 15 minutes (900s) |
1 hour (3600s) |
medium | SOA TTL is below typical — observed 15 minutes (900s), 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. |
| 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-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.

Alias record TTLs fixed at 60s
RFC 1035 §3.2.1
AWS Route 53 alias records pointing to AWS resources (ELB, CloudFront, S3, API Gateway) have a fixed TTL of 60 seconds that cannot be modified. Route 53 alias records are an AWS-specific extension — not part of standard DNS RFCs. They solve the CNAME-at-apex problem (RFC prohibits CNAME at zone apex) by appearing as A/AAAA records to resolvers. The 60-second TTL ensures fast failover but removes administrator TTL control.
Proprietary extension — not covered by DNS RFCs

Email Security Methodology Can this domain be impersonated by email? Yes DMARC is monitor-only (p=none)
SPF Record RFC 7208 §4 Verified
Does this domain declare who may send email on its behalf?
Yes
Success
~all
7/10 lookups
SPF valid with industry-standard soft fail (~all), 7/10 lookups

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 has DMARC p=none (monitoring only). Enforcing quarantine or reject is recommended to gain real protection.
Legacy Record — Safe to Delete
This is a Sender ID record (
spf2.0/pra) from a Microsoft experiment circa 2006 that was never standardized. RFC 7208 §A explicitly deprecates it. No modern mail receiver processes this record. It is safe to delete.

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.

DMARC External Reporting Authorization RFC 7489 §7.1

Authorization missing
Warning
1 of 1 external reporting domains missing authorization
| External Domain | Authorization | Auth Record |
|---|---|---|
webservice.team |
Unauthorized | — |
External domain webservice.team has not authorized hortongroup.com to send DMARC reports (missing hortongroup.com._report._dmarc.webservice.team TXT record)
Third-Party Action Required
This authorization record must be created by the external reporting provider, not by you. Per RFC 7489 §7.1, the receiving domain must publish a TXT record to confirm it accepts DMARC reports from your domain.
What to do: Contact your DMARC reporting provider and ask them to publish the authorization TXT record shown above. If you use a managed DMARC service (e.g., Ondmarc, Dmarcian, Valimail), this is typically handled during onboarding — reach out to their support if the record is missing.
Impact if unresolved: Compliant receivers may silently discard aggregate or forensic reports destined for the unauthorized address, reducing your DMARC visibility.
DANE / TLSA Verified Recon Methodology Can mail servers establish identity without a public CA? No
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).
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 is monitor-only p=none (RFC 7489 §6.3) — spoofed mail is not blocked, brand faking is trivial

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.

DNS History Timeline BETA
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.
72a63d79f00b96190b64d1d0cbc719ec3aca162f25a72a4191026de8e8068fd2794110687a1b2a4be5b79e1faf4661271506bcb6db27666312eda73d9a866122
Evaluations reference 12 RFCs. Methods are reproducible using the verification commands provided. Results reflect DNS state at 9 Mar 2026, 18:00 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-hortongroup.com.json.sha3 && echo '---' && openssl dgst -sha3-512 dns-intelligence-hortongroup.com.json
Python 3 (cross-platform)
python3 -c "import hashlib; print(hashlib.sha3_512(open('dns-intelligence-hortongroup.com.json','rb').read()).hexdigest())"
sha3sum (coreutils 9+)
sha3sum -a 512 dns-intelligence-hortongroup.com.json
Compare the output against the
.sha3 file or the checksum API at /api/analysis/6949/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 hortongroup.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.
