Figure out live hosts on a network
I'm trying to figure out the best way to find all live hosts on a Class C network.
1. What is the best way to figure out all the subnets that are being used?
2. Assuming that ICMP is allowed, would using something like Hping be more efficient, or NMap?
Pinging broadcast address
Nebulus-
I had thought of that, something like pinging all the xxx.xxx.xxx.255 addresses. However, how would you do that. Lets say I pinged a 192.168.0.255 address. Would that broadcast it to the entire 192.168.0.xxx address and return the response to my IP address?

Depends a little on your setup, but yes. .255 means every computer on the network (C level)...technically so does .0 ...
