Every now and then you forget what all is on your network. Or you forget the IP address at which a certain device resides. How to find out what's out there? There are a couple of ways to scan the network and see what's out there:
nmap scans the range you select:
nmap -sP 192.168.47.0/24 (the "P" stand for ping)
ping the multicast address of 224.0.0.1 (all hosts)
ping 224.0.0.1
Well behaved devices that understand multicast addresses will answer the ping.
OK, there's nothing earth shattering here, but sometimes I forget syntax and I need an easy place to look it up......
