DisplayExternalIP
by DevEx
DisplayExternalIP shows the player's external IP address as a window title in the top left corner of the game, so the address in use is visible at a glance.
What it does
Players who route traffic through a split VPN tunnel can check which address the game is using before joining a server. The external IP appears in the window title and in the top left corner of the screen, so a player can confirm the connection goes out through the intended route.
The mod runs on Fabric for 1.21.3, where the only published file is version 1 of 2024-11-27. Fabric API must be installed alongside it. Only the client needs it, and the mod is released under the MIT License. It is not open source. The file is not connected to any server-side setup, so server owners can leave it out.
