Open Port Checker

Scan a specific port on an IP or domain to see if it is open and listening. This is useful for testing Port Forwarding configurations, checking for firewall blocks, or verifying if a service is running.

Common Ports to Check

• Port 80 (HTTP) / 443 (HTTPS): Web Servers.
• Port 25565: Minecraft Servers.
• Port 3389: Remote Desktop Protocol (RDP).
• Port 21 (FTP) / 22 (SSH): File transfer and remote administration.
