Scan for all subnets or even better - scan for MAC adress?

Scan for all subnets or even better - scan for MAC adress, is it possible?
Need to make map of network, but need to do it fast :frowning: no time to get familiar with the network and all subnets :frowning:

Is there a solution?

Yes definitely set the dude to scan 0.0.0.0/32. Set it to install all probes too!!

HURRY!
