This document summarizes a project that implemented IPv6 and enabled cross-platform communication between IPv6 and IPv4 devices. The project involved compiling a new kernel with IPv6 support, setting up a lookup service to register IPv6 clients, configuring DNS to resolve IPv6 and IPv4 names, and testing cross-platform communication between an IPv6 server and IPv4 and IPv6 clients. The conclusion is that the project provides a scalable and secure IPv6 solution to resolve long-term addressing issues and allows communication across different platforms.
