Thanks for the link the prob is only that i am working from the office and here they don't have formats like tar and I don't have any Linux station next to me (sadly)so there is the prob (especially because I don't even have WinRaR or something like that)

It looks like that's what you asked for. I'm not sure what the problem is.

The problem is that i need every IP only once. (Sorry if i didn't say that before). So i only need to get the IPAddress and not also the NEIGHBOURIPAddress, bacause then i have everything only once.
