How To Use the Port Checker Tool

The open port checker tool by default automatically detects the gateway IP address that the computer is on that you are accessing this page from and populates the IP address / host name field. You can manually change that field to any IP address, domain or host name that you want to test. You do not need to be at the location of the IP address or domain that you are testing in order to use this tool. Next, type the port number that you want to test in the port field and click the scan button. You can also just click on one of the commonly used ports for surveillance equipment on the right and the scan will begin for you using the port(s) that you clicked.
