Hi,

I have built a C# client-server application. The client connects to the server running on a remote machine by using its IP Address. I have used System.Net.Socket.TCPClient for client and System.Net.Socket.TCPListener for the server.

The application is wokring fine for normal IPv4 address, but when i try to connect to an IPv6 address it fails. The client throws the following exception: No such Hosts Found.

Please help.

Solution 1

There's a sample from Microsoft here[^] that gives a clear solution you might use as a reference. One thing I note is that the article is for .Net 4. It's possible that previous versions of the TCP-related methods don't work with the IPv6 standards, and you may be using an earlier version for your development. If so, try rebuilding the solution using .Net 4 and see if that changes anything.
