Registry Zone Health Report
Read the verdict first. Descend only as far as the incident requires.
This report keeps the complete technical record while separating decision, interpretation, evidence, and raw reproduction into a stable disclosure gradient.
DNSSEC is not enabled for this domain. DNSSEC provides cryptographic authentication of DNS responses, preventing cache poisoning and DNS spoofing attacks.

CAA RFC 8659 §4 N/A
CAA records on a TLD zone do not constrain certificate issuance for domains registered under this suffix. Per RFC 8659 §3, CAs process CAA by climbing the DNS tree from the requested FQDN — a CAA record on the TLD itself would only affect certificates for the bare TLD, not for child domains like example.test. No major TLD publishes CAA records.
Delegation Consistency 2 Issues
Delegation consistency: 2 issue(s) found — Parent/child NS delegation alignment: DS↔DNSKEY, glue records, TTL drift, SOA serial sync.
- Could not retrieve NS TTL from either parent or child
- Could not retrieve SOA serial from any nameserver

DNS Server Security Hardened
No DNS server misconfigurations found on localhost — Nmap NSE probes for zone transfer (AXFR), open recursion (RFC 5358), nameserver identity disclosure, and DNS cache snooping.

| Zone Transfer (AXFR) | Denied | Test inconclusive |
| Open Recursion | Disabled | Test inconclusive |
| Nameserver Identity | Hidden | Test inconclusive |
| Cache Snooping | Protected | Test inconclusive |

06^6 Raw records & reproducibility · L2–L3 Evidence & Verification Can another engineer reproduce every material claim? Analysis Confidence Intelligence Currency What changed Raw record diff Integrity seal Reproduce
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 | 3 hours (10800s) |
1 hour (3600s) |
medium | SOA TTL is above typical — observed 3 hours (10800s), 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-7 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.

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.

After downloading, verify with any of these commands:
Tip: cd ~/Downloads first (or wherever you saved the files).
cat dns-intelligence-test.json.sha3 && echo '---' && openssl dgst -sha3-512 dns-intelligence-test.jsonpython3 -c "import hashlib; print(hashlib.sha3_512(open('dns-intelligence-test.json','rb').read()).hexdigest())"sha3sum -a 512 dns-intelligence-test.json.sha3 file or the checksum API at /api/analysis/15811/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 test. 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.
