How to Check a Port Ping
A ping is an application used to test the network connection between two computers. It sends data packets over a network, or the Internet, to a particular computer to test the connection. It is also used to test the connection to a specific port on the recipient computer. A port is simply a docking point that two computers use to communicate. If you do not enter the correct port when completing a ping, the recipient computer will not establish the data connection.

Obtain the IP address and port number of the computer you want to ping. This information is only available from the user of the computer you want to ping. You cannot guess someone's individual IP address. However, the IP address will resemble this general format: "127.0.0.1:121." In this example, the port number is 127.0.0.1 and the port number is "001." The IP address and port number must be separated, without a space, with a colon.

Wait several seconds for the program to initialize. The program has initialized when a window labeled "Windows Command Prompt" opens and a blinking cursor appears.

Type PING and the IP address, followed by the port number you want to test. For example, ping your own computer's network connection by typing "Ping 127.0.0.1:121", where 127.0.0.1 is the computer's IP address, and 121 is the port number.

View the results at the bottom of the Windows Command Prompt Screen. A successful connection returns a result that looks similar, format-wise, to this:
"Ping statistics for 127.0.0.1:121 :
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss)."
In this example, the computer was able to successfully send and receive data from the other computer.
