I am looking for a network scanner that will ping and list responses. I am trying to build a list of internal ip address assigned, then I can feed it in to another program I have and it will pull all the info off the supplied ip's. Problem is, I can use the program I have to scan, but there is no options anywhere to ignore non responsive hosts, so it take for ever. But it does have an option to import ips from a text file. So the scanner I'm looking for has to be able to export to text file.
