This app is extremely simple and does what it says it does. You plug in your list of network devices IPs or hostnames and you can then with one button click on the main screen ping them all and see whats online or offline. If you work in an organization that has standardized device naming by location or room number, you can simply add a list of standardized device names and replace the location or room number with the text {V} and then enter that info later on the main screen. The results of the ping will show the current online status as well as the latency of the ping that was sent.
