Just to clarify — LAN mode is an optional feature, not the only way the app works. By default ONYX works like any other messenger through a central server, with E2EE for private chats (unlike Telegram, where only Secret Chats are E2EE). LAN mode is an additional feature for people on the same local network who want to communicate without any internet or server involved at all — useful for office environments, local events, or situations where internet access isn't available or isn't wanted. So to answer your question: in normal mode, the server handles routing. In LAN mode, UDP broadcast handles discovery automatically — no manual IP tracking needed.
That's neat! Thanks for taking the time clarifying.
