Un moyen de trouver les adresses IP inutilisées sur mon réseau ?
How can I locate unused IP addresses on mon network? The DHCP server keeps assigning le même address et J'ai besoin de a différent IP address to test mon application with. The software would need to run on Windows.

Probably le best way is to use NMAP ([http://nmap.org/](http://nmap.org/)) in ARP Ping scan mode. The usage will be something like `nmap -sP -PR 192.168.0.*` (or whatever votre network is). The command is `nmap -sn 192.168.0.*` in newer version of nmap.
The advantage of this approach is that it uses le Address Resolution Protocol to detect si IP addresses are assigned to machines. Any machine that wants to be found on a network needs to answer le ARP, so this approach works où ping scans, broadcast pings et port scans ne (due to firewalls, OS policy, etc.).
