IP Scanner might prove to be of good use to system administrators for easily identifying the devices that are being connected to their local area network. The program is very intuitive, immediately completes the scanning process without slowing down your Mac, and provides you with accurate and detailed information.
As soon as you launch the utility on your computer, it automatically starts scanning your local area network. You can use this tool for free if you're dealing with a small-sized network (not more than 6 devices). Otherwise, you would need to register the product on the homepage of the developer. Still, the price is quite reasonable, especially if you plan on using this program often.
You have access to a detailed results list which you can easily sort according to your needs. What's more, you can assign various tags to the connected devices for an easier identification.
Another advantage is the fact that you can print or export the offered information to your local folders.
The only thing you need to consider is that you can find cheaper solutions for identifying the devices that are being connected to your LAN. They aren't as feature-rich as IP Scanner but they provide you with accurate data. So, I'll leave it to you to decide which is the best solution for you.
