Port Checker is a simple and free online tool for checking open ports on a computer/device, often useful when testing port forwarding settings on routers.

For example, if one of your programs (email, IM client, etc.) is having connectivity issues, the ports required by the application may be blocked by your router firewall or by your ISP.

In this case, this tool can help you diagnose problems with your firewall settings. You might also find this useful for security reasons, in case you're not sure if a particular port is open or closed.

If you host and play games like Minecraft, use this checker to make sure the server port (25565) is properly configured for port forwarding, then only your friends can connect to your server.

A port scanner, also known as an open port scanner or IP port scanner, is a free tool that shows which ports on a network are available for communication.

When setting up IP security cameras, it can be helpful to determine whether ports are open. Also, it helps to determine if the network is secure.

You can use a port checker or port scanning tool to check other network-related operations and network management functions.
