Worked on enhancing the private networking documentation within the railwayapp/docs repository by developing a practical, runnable example using Rust and the Axum framework. The contribution focused on demonstrating how to bind network services to both IPv4 and IPv6 addresses, providing clear guidance for users setting up private networking environments. This work involved writing detailed documentation in Markdown and implementing the example in Rust, with attention to networking concepts and real-world usability. The update addressed a common need for comprehensive, actionable documentation, improving the onboarding experience for developers working with private networking features. No bug fixes were recorded during this period.
