What it does

Queries A, AAAA, MX, TXT, NS, and CNAME DNS records for a given domain

Command maturity: Alpha

Available for real use and feedback while its interface and behavior can still evolve. This is the current development-checkout assessment. Every future immutable release tag preserves the exact assessment shipped by that version. Available in PyPI 0.2.2.0.8. This page documents the 0.2.2.0.8 alpha development checkout.

Behavior and built-in protections

Inspects without changing state

Direct execution for this operation

Uses a native tool when needed

Uses network access for the documented task

No elevation required by design

Errors and limits

The public contract requires success=false and a descriptive message on failure. This catalog does not yet declare a command-specific error taxonomy; inspect the result and do not invent error codes.

QZX is alpha software. Optional dependencies, permissions, and host capabilities can change the result.

Evidence workflow: requires an authorized endpoint or reviewed fixture.
