Is there a way to (check/scan through network) ip addresses of listening ports in a network

Probably you have to connect to it, if you get an exception -> port closed, otherwise successfull, then close it.

If you put the server listining you will(or not) accept clients and by that get their ip. Having the ip´s send whatever package you want to. I assume that you didn´t start yet. Download some application here and see the code, if you have doubts ask here then.
