What is Port Scanner?
The port scanner checks which network ports are open, closed, or filtered on a target IP address or hostname. It scans common service ports like HTTP (80), HTTPS (443), SSH (22), and FTP (21), or custom ranges you specify. This helps identify running services, detect security vulnerabilities, and verify firewall rules.
