🔧 Fix this

Ideas a builder, maker or community group could start on:

  1. Develop a lightweight, open-source peer-to-peer relay tool that automatically bridges IPv6-only services to IPv4-only networks without third-party cloud dependencies.
  2. Create a diagnostic mobile app that identifies whether a specific carrier or network environment is blocking IPv6 connectivity for the user's home server.
  3. Publish a standardized, automated configuration script or 'plug-and-play' hardware bridge that simplifies IPv6-to-IPv4 tunneling for non-technical self-hosters.
