I am looking for a Software, that can scan a network and display me the IP addresses of the router and the switches.
The Network is pretty big.
I need it because everything is just plugged together anyhow and I want to bring structure into it. Before doing that I need to know the current configuration.
Starting from scratch would not be a possible solution, because it's a running System which is used 24/7
Free Tools are preferred but aint a must
