About Port Checking

Port checking is useful for troubleshooting network connectivity issues, verifying firewall configurations, and ensuring services are accessible from the internet.

Note: This is a simulated port checker that randomly determines if ports are open or closed for demonstration purposes. In a real production environment, this would connect to a backend service that performs actual port connectivity tests.

For comprehensive network diagnostics, consider running a full speed test.
