in reply to batch ping problem

thanks for the help monks. I think i should have made my idea here a little clearer: I want to find ip's that don't return anything, so I know that they are free to put a new machine on. anyway, I knew there was some easier way to do it. I'm still a newbie, which is why I asked what I could do to make it more simple--newbies usually do things the hardest way possible. Thanks again.
