Netcut is a free Windows tool designed to scan the computers in your network and provide information on every single machine.
While you may find the interface a bit unprofessional, you need a few minutes to figure out where to start.
netcut automatically scans your network and retrieves information on the connected machines, with dedicated tools to find a specific IP. A very good feature is the one that allows you to choose a different network adapter in case you're using multiple ones at the same time.
The main window is being used to display the current status of a specific IP (on or off), the IP per se, the hostname and the physical address, which is actually the MAC address of a connected system.
And speaking of MAC addresses, netcut also comprises a dedicated MAC spoofing tool that enables you to change the physical address of the selected network adapter with just a few clicks.
Unfortunately, the interface seems to be a major drawback, not only because beginners may get lost in it after launching the app, but also due to the fact that all buttons are grouped above the IP list panel.
On the good side however, netcut works like a charm on all Windows workstations and it doesn't seem to affect system performance at all, without even asking for administrator privileges when loaded on Windows 7.
