Overview
The safe_url_check package enables secure validation of untrusted URLs by verifying their accessibility without establishing actual network connections. It prevents potential security risks by blocking access to private IP addresses and ensuring only safe, publicly reachable URLs are processed. Designed for use in environments where URL integrity and safety are critical, it provides a lightweight, reliable way to check URL validity while maintaining strict security boundaries. The package is particularly useful in applications that handle user-provided links or external resources.
