I have a script I wrote in UNIX that will go and ping all IP's in a certain subnet. If you have any UNIX/Linux experience, I'd be happy to share it with you.
Of course, this will only tell you which IP's are in use at that moment in time. There could still be IP's in that subnet that are used but on devices that aren't turned on at that moment in time.

You could also use a scanning tool like Angry IP Scanner (www.angryziber.com) that scans a given network for all IP addresses and ports.

You would only see the IP's that report.
"Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10

The "used" IP addresses in a network will be the DHCP pool (if the network is running a DHCP server) + all the statically assigned IP addresses on the network. If you don't have that information available for your network, then unless it's a small network, you've got a mess on your hands.
