Of course you can communicate with a server without having it's address!
In the same way that I'm communicating with you without knowing your address: using a #nostr relay to deposit and get the note...
Sure, if two parties rely on a third party to act as a sort of proxy to hold messages for them, then both parties can just connect to the proxy.
That is a form of "communication", but it's indirect. I was talking about making direct connections, because that seemed to be the spirit of the OP
