I have recently channged my ISP because they kept upping the cost but not the data rates. Of course that created havoc on my home network. Replacing the router, new wireless access and for some reason problems with some static and dynamic IP addresses. This tool was an easy way to get a look at the network and see what was going on. I really liked the fact that I could assign my own names to devices, like IP Camera’s by location, which makes the tool very easy to use once it is set up. You can also assign an icon for the device… Great if you are a visual person. Some other tools seem to think that they need a lot more features. And, I have used them on occassion to debug problems. But,they are not all kept up-to-date and my old tool just refused to work on MacOS 10.10.1. I recommend you try the free version, if you have less than seven devices, it is sufficient. But the home version is pretty inexpensive, seems to be kept updated, and handles 22 devices, more than enough for most home users. It provided the basic functionality to debug simple problems like IP address conflicts. Value for the small cost is great.
