Scan, validate, preview, normalize, and expand IPv6 addresses across files and folders.
The extension is focused on RFC 5952 compliant formatting with safe preview-first workflows.
Highlights
- RFC 5952 normalization for IPv6 addresses and prefixes
- Expansion to long IPv6 form
- Selection-only conversion from the editor context menu
- File and folder preview reports as Markdown (with diff blocks)
- Clickable jump links to file/line/column from preview and reports
- Live diagnostics and Quick Fix actions in editors
- Recursive folder processing with progress and cancellation
- Optional change highlighting in open editors
- Localized UI (EN, DE, PL, CS, FR, ES, IT, RU, JA)
