What is an Open Port Checker?

An Open Port Checker is a free online utility designed to scan your external IP address or hostname for open ports. It helps you determine if a specific port on your router, firewall, or server is accessible from the internet, ensuring your server configurations are operating correctly.

Why is Online Port Scanning Crucial?

Testing your connection for open ports is vital for both cybersecurity and network performance. Our advanced port scanner helps you:

  • Verify Port Forwarding: Ensure your router settings are correctly routing traffic for applications like gaming servers, torrents, or remote desktops.
  • Audit Network Security: Identify accidentally exposed ports that could leave your server or local network vulnerable to cyber threats.
  • Test Firewall Configurations: Instantly check if your web server’s firewall is successfully blocking unauthorized external traffic.

Common Ports You Should Test

Many critical internet services rely on standard port numbers. You can use our online tool to check critical ports such as:

  • Port 80 & 443: Standard web traffic (HTTP / HTTPS).
  • Port 21 & 22: File transfer and secure shell access (FTP / SSH).
  • Port 25 & 587: Email delivery servers (SMTP).
  • Port 3389: Remote Desktop Protocol (RDP).
