This project provides a PHP-based tool for checking domain names against various DNS servers and security blacklists. It offers both a web interface and a command-line interface (CLI) for flexible usage.
- Comprehensive DNS Checks: Verify domain accessibility and security across multiple DNS providers.
- Categorized DNS Servers: Test against normal, secure, and ad-blocking DNS server lists.
- Custom DNS Configuration: Add your own DNS servers for tailored testing.
- Security Intelligence Integration: Links to reputable security services for threat assessment.
- Modern User Interface: A responsive web interface built with AJAX for real-time results.
- Command-Line Interface: A powerful CLI tool for automated or script-based domain analysis.
- PHP 7.4 or higher
- Command-line tools:
dig,nslookup,sed,head,awk,sort,dirname,readlink(some are OS-dependent)
