A ver Challenging Question!!!

[kourosh]

Hi all, I asked tis question before and nobody answered and I think it is a pretty though one! Well the problem is I am creating a chat program and I need my program to return all the IP addresses exist in the network to a list box or a variable array, well that is not important where to store the IP's. The important think is how to get them all???

Well I am not sure if anyone can answere this one. But if you can, I know you are pretty smart.

Damn, hey man, you are going to need some kind of a port scanner, as far as i know, the only time ive ever seen every ip address listed is the server....

Are you sure about that??? Well is there anyway to make a port scanner with visual basic. I want the program to do everything. I mean I don't want to use any outside programs.
