This is a small chat program in Java, that uses the IP addresses of the conversational partners to send messages through the web. No web server is used to exchange messages between two or more participants, but all messages will be send directly to the recipient. You have to enter the IP address of the end device the person uses you want to chat with. A request will be sent to that person. As soon as the request will be accepted the conversation is able to start. You can save IP addresses of chat partners you want write to frequently and name them in an arbitrary way.
