Ping a computer using Network Utility on Mac
Use Network Utility to see if your computer can communicate with a computer or other device at a specific network address.
This type of test is called pinging the other device. Pinging can help you figure out if a communication problem is caused by your computer, the connection, or the remote device.
Ping any device that uses Internet Protocol (IP), such as a computer, network printer, or AirPort device.
On your Mac, open the Network Utility app , located in the /System/Library/CoreServices/Applications folder.
Enter the IP address or DNS name of the device you’re trying to contact, then click the Ping button.
If the other device responds to your ping, your basic connection is good.
If the other device doesn’t respond, try pinging devices in other locations to determine if the problem is with your network connection or with the remote device.
For help interpreting the results, or to see how you can use the underlying ping command to fine-tune your troubleshooting, open Terminal (in Applications > Utilities), then type man ping at the command line.
