With Dipiscan, you will be able to scan IP ranges, retrieve information from a machine from its IP address, NetBIOS name, or DNS, find the network "road" taken to get another machine, and you can monitor a machine to see the changes since the last scan. It additionally includes a configuration dialog that will allow you to configure system operations and micromanage them, and you can also extend the right-click menu with custom commands. It comes in both portable and installer versions.
The UI is simple and uncluttered, lending itself usable to any user skill level. It performed fast for us during testing without any issues.
