Invaluable Tool
As someone constantly adding devices to, removing others from, and/or tweaking my network at home in other ways, I have found this app to be essential in troubleshooting conflicts in IP assignments or identifying mysteriously disappearing DHCP reservations. I find I use this app so often that It has even earned a spot on my (self-proclaimed) coveted Launcher. While there are a few UI/UX quirks in the app, they are vastly overshadowed by its usefulness. It is very highly recommended!
