This GitHub Action is designed to automate the validation of DNS zone files and BIND configuration files (named.conf) using named-checkzone and named-checkconf. It builds upon the features of the original action-named-checkzone with enhancements aimed at speed improvements and addtional checks.

• Zone File Validation: Validates DNS zone files for syntax correctness using named-checkzone.
• Configuration Validation: Verifies the syntax of BIND configuration files (named.conf) using named-checkconf.
• Automation: Automatically runs on push and pull_request events, ensuring all changes are validated.

• Alpine Docker Image: Utilizes a smaller Alpine-based Docker image, reducing the overall runtime footprint.
• Dynamic Zone Name Extraction: Instead of relying on zone filenames, this action extracts zone names directly from the $ORIGIN directive in zone files, ensuring greater accuracy and flexibility.
• Enhanced named.conf Validation: Specifically targets and verifies configuration files formatted like named?.conf, ensuring only relevant BIND configuration files are checked.

This project is based on and extends action-named-checkzone by @grramos. I want to express my gratitude for the groundwork laid in the original project, which inspired my enhancements.
