Server find all clients dynamically?

I was reading through the documentation, and couldn’t find any reference to a server finding all clients on the network. 

I see that bonjour is setup on the server to broadcast out to clients, but not the other way around.

From the server side, I see that reverse connection is a new feature. It allows the server to connect to static ips (which is great), but didn’t notice a way to have the server find all current clients on the network.

Is there a built in way to find all clients dynamically from the server and I just missed it in the documentation?

Thanks,
