I have made a chat program to work over my local network, the thing is the only way it works is if you have the computers IP address or by using the built in IP scanner (WHICH CAN TAKE AGES).
I was wondering if there was a way to find all the IP addresses on the network so it can quickly go through them and see which people are running my chat client and so we can chat till our hearts content.
If any dos command available please post...... :)
Advance thanks :)
Which programming language do you need it? Have you tried searching here or googling for it?
If this is running over a LAN why not use the Computer name(s) rather than IP Addresses?
I am sorry for didnt mention the language.... I need vb only.... Thanks for your links.... Try it now... :)Quote:

i'd do it in a backgroundworker so as not to make your app appear slow, and set the timeout to a low value if the computers are on the same network.
Code:Dim ipLIST As List(Of String) = ipRange("192.168.1.1", "255.255.255.0") 'get list
Dim ipFND As New List(Of String)
'in a backgroundworker
For idx = 0 To ipLIST.Count - 1
If My.Computer.Network.Ping(ipLIST.Item(idx), 1) Then
'found one
ipFND.Add(ipLIST.Item(idx))
End If
Next

Thanks for your reply..... Buddy I need vb code for finding out... But your IP / Subnet Range link is vb.net...
That C# code works perfectly.... Thanks dee-uQuote:
