Ok so I had an idea for a script and I hope someone takes the time to do it because I would really love having this script. So my idea is a IP monitor. A script that would ping IP's from like 10 to 10 seconds or so. The script would inform when the IP goes online aka when the ping has a response and would inform the user when the IP goes offline aka when the ping stops having a response. It would be cool if you could insert many IP's in the script and put the name of the owner of that IP, so the script instead of saying that a IP is online it would say that a person's computer is online or offline. Please can someone do it? I really want something like this and don't have a clue how to script.
