Advanced PortChecker is a free application that you can use to scan an IP address for open ports. You can scan both TCP and UDP ports (at the same time) to check if they are allowing connections. Scanning information is displayed in real-time meaning you can already use the information as soon as it’s available!

Please only scan networks that you have permission to scan.
