I found this article that contains code on a client / server application can communicate with each other without knowing their IP address prior the the first network handshake. The article discusses using UDP.
http://www.nullskull.com/a/1551/clientserver-autodiscovery-in-c-and-udp-sockets.aspx
My understanding of UDP is that it is not as secure as TCP.
Is there a TCP example?
Or any other advice? I need a client to auto discover a server app without knowing the IP. I know bonjour is a possibility but looking for another solution.
Thanks
