In P2P(peer-to-peer) networking, it is possible for the server program(software) and the client program(software) to be running on the same computer.
So the two must have the same IP address.
I am confused about this. Is there nothing going wrong if both of them uses the same IP address?
Please clarify.
Sure. That's fine. Nothing wrong with that. Transport-layer protocols (such as UDP or TCP) use port numbers so that you can run multiple applications on the same machine without any difficulty.
