问题 I'm currently writing a Java application that uses TCP/IP to communicate. What i'm trying to accomplish is to get the client to easy find the server and connect by sending some message out. The question now is: What can i do to make the client discover the server? Is there a way i can send a message to the router (DHCP-server maybe) that tells it that I'm using this service?
