There are times when it can be handy to know which other devices are on your local network.

How to Use Ping

For example, suppose that you need to know whether a certain device such as a computer, tablet or router is up and running and responding. Ping can be used either in the command line form, or from within Network Utility , and there are also lots of other free apps which can help you to build up a local network map by way of using the ping command.

This article shows you how to determine the IP addresses of all devices connected to your local network.


Some versions of UNIX on which OS X is based include a special version of ping which lets you send a broadcast message that every device receiving it will respond to. Unfortunately, OS X does not include this version, but there is another way to get most devices to respond.

Now, you need to look for any 0 values in the subnet mask, turn them into , and put them into the same position in the IP address field, and then ping that network address. Every device on your local network should respond to this ping. This is really meant to be an example as I've not coded it to account for the device being down.


In other words if the device doesn't have and IP Address there will be no output to stdout and nothing assigned to the ipAddress variable in the script. Although in the script it can be coded to test whether or not the ipAddress variable is empty and act accordingly. From there you can get the gateway and mask, etc - in python I use netifaces for that.
