Client server question
I would like to create a chat program that connects phone to phone directly, each phone being both a client and a server.
How do I make a direct connection to a phone??
Find out the IP?
But don't the IPs change over time?
If so, how do I compensate for the changing of phones IP address?

At least one client needs to know the IP of the other one. Yes, most IPs do change over time.
Normally you would compensate for this by having a centralized server with a static IP that clients communicate with to form some mapping between a static identifier (like a username) and their corresponding dynamic IP address.
