i have a problem with my client/server program. I can connect the client to the server over the internet only if I know the IP address of the server , and because my ISP gives me a > address every time I connect to the internet I want to ask if there is an easy way so that the client can get the servers IP automatically
I'm programming in C with mingw32 (gcc) for win32. thanks

I can think of two possibilities.
1) Usually there will be a range of possible IP addresses that your internet provider can assign to you. You could try them all until you find the one that will respond. Your provider may not like you pinging all the other customers, and they may think you're trying to hack them or something, but it would work.
2) Use a third party server that DOES have a static IP address. For example, when you log in, have your server FTP into your internet site and deposit a file with his IP address in it. Then your client can FTP in and pick up the IP address.

You can also use a dynamic dns server like the one at www.dyndns.org
