DNS Inventory

Use only for a domain in the authorized scope. Prefer an owned local zone or a passive data source. Do not perform broad third-party enumeration.

Phase 1: bounded inventory

Record the target domain, scope, resolver, timestamp, and source. Query only the necessary records and subdomains needed to document the owned surface. Keep request volume bounded and write results under the local case directory.

Phase 2: verification

For each discovered record, verify ownership and expected routing with a normal DNS query. Do not attempt takeover, credential collection, or service access.

Output an inventory with evidence, confidence, stale-record candidates, and remediation. A missing authorization or non-local target stops the active phase.
