Is it possible in windows cmd line to check all of the network addresses (with ping or similar) to see which ones are taken/ have active devices:
ie. something that does
Best Utility in terms of speed is Nmap.
write @ cmd prompt:
Nmap -sn -oG ip.txt 192.168.1.1-255
this will just ping all the ip addresses in the range given and store it in simple text file
It takes just 2 secs to scan 255 hosts using Nmap.
