Organizational domain for com.au could not be determined — the Public Suffix List compiled into this build does not recognize the suffix. Email-security scope below is not determinable; this is not a finding that the domain is or is not a subdomain. Re-run when the PSL snapshot is updated.
Registry Zone Health Intelligence — com.au is a shared registry suffix.
This report focuses on zone infrastructure health: DNSSEC signing, nameserver diversity, certificate authority policy, and delegation security. Email authentication protocols (SPF, DMARC, DKIM) are not applicable to registry suffixes — they apply to domains registered under this zone.
Registry operators, ICANN, and ccTLD authorities can use this view to assess zone security posture.

Critical Publish SPF record

SPF (Sender Policy Framework) tells receiving mail servers which IP addresses are authorized to send email for your domain. Without SPF, any server can claim to send as your domain.

RFC 7208 §4
Critical Publish DMARC policy

DMARC (Domain-based Message Authentication, Reporting & Conformance) tells receivers how to handle messages that fail SPF/DKIM checks. Without DMARC, failed authentication checks are ignored. Start with p=none and rua reporting to monitor, then escalate to p=quarantine and p=reject.

RFC 7489 §6.3
Medium Deploy MTA-STS policy

Publish an MTA-STS DNS record and host a policy file at https://mta-sts.com.au/.well-known/mta-sts.txt. This tells senders to require TLS when delivering mail to your domain.

Analyze Another Domain

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), SecurityTrails (DNS history), 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.

Download Raw Intelligence Download Checksum (.sha3) Cross-Reference Verification

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-com.au.json.sha3 && echo '---' && openssl dgst -sha3-512 dns-intelligence-com.au.json
Python 3 (cross-platform) 
python3 -c "import hashlib; print(hashlib.sha3_512(open('dns-intelligence-com.au.json','rb').read()).hexdigest())"
sha3sum (coreutils 9+) 
sha3sum -a 512 dns-intelligence-com.au.json
Compare the output against the .sha3 file or the checksum API at /api/analysis/783/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 com.au. 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.
