Open Port Checker - Test Open Ports & External IP

Test Open Ports & Network Accessibility

The Open Port Checker is a simple yet powerful tool that lets you check your external IP address and identify open ports on your connection. Open ports can be used by services, applications, or potentially by attackers if left unsecured.

With this tool, you can:

  • Detect open ports on your network.
  • Verify if specific ports are accessible from the internet.
  • Troubleshoot port forwarding configurations.
  • Ensure that only intended services are exposed.
  • Strengthen network security by identifying unnecessary open ports.

Simply enter the port you want to check, and the tool will test if it is open on your external IP address. Perfect for sysadmins, IT professionals, gamers, and anyone setting up port forwarding.
