Tools & Capabilities Breakdown

Dns Doctor Tools (17)

scan_domain
Fresh scan of a domain; full report.
get_report
Persisted report (scans once if none exists).
build_dmarc_upgrade
A validated DMARC enforcement record, capped at `p=quarantine` and returned only when the server-derived alignment gate passes; without that evidence the answer is reporting-first and no record is returned. `p=reject` comes from the readiness engine's aggregate-report evidence, never from a scan.
count_spf_lookups
The SPF DNS-lookup count against the RFC limit of 10.
validate_dmarc_record
Parse and validate a DMARC record, tag by tag.
generate_dmarc_record
