Im not exactly a professional but i think what you need is called a port scanner, you can implement the very basic functionality of a port scanner into your app and read all the live ips in your network

one solution would be: http://www.geekpedia.com/tutorial142_Creating-a-Port-Scanner-with-Csharp.html

they even have code available for download on the site. haven't tried downloading it tough. :)
