Let me first explain my situation:
I am currently in the process of trying to build a solution for managing multiple Internet of Things devices on a network. It should be possible to automatically make the clients connect to a central server which is hosting an MQTT-Broker.
In IPv4 networks, I would simply send a broadcast packet from the client, to which the server would respond with a packet containing its own IP address. Now that the client knows the IP address of the server, it would be able to connect to it after this.
However, things are different with IPv6, since there is no broadcast anymore. How could I make my client automatically find the server without hardcoding a multicast address?
