I know this is a bit of a custom requirement but I was hoping someone currently has (or can put together) a script that checks for duplicate IP addresses on a network (something that might occur when someone assigns their own static IP when that lease has already been handed out via DHCP).
I know that it would be better to simply prevent them from changing it but with students coming in with their own laptops, etc, this is often a problem. I only have a single classroom with about 20 students so once I know the IP (that is duplicate) and preferably the hostname, I can take the necessary steps.
Emailing the script is ideal because I can get it when I am out of the classroom and on my mobile.
Thanks, hope someone can help me out with this.
