Netviz (short for NETwork VIsualiZer) is a Python program I cobbled together for a user to monitor devices on the user's LAN or a small section of the Internet. Essentially, it's a pretty interface for information on the MAC addresses and IPs of those devices. The range to search can be set either by the boundaries of the user's LAN using the "Find Range" button or through user-typed IPs. Also, there is a list of tracked MACs. If any of these tracked MACs appears on the LAN, the program shows the IP of this MAC.
Simple to use.
thank you net-viz
Love this even as an early release. Nice simple GUI. Albeit you need pygame. It's a nice alternative to big clunky packages that you only use several utilities from. No bloating here!
