IPv6-Only Transition Roadmap

This chapter discusses the history and future directions of IPv6 transition, and it also presents a roadmap for adopting IPv4-reachable IPv6-only networks, addressing the critical need to overcome IPv4 address exhaustion while ensuring continued connectivity. It emphasizes selecting transition technologies that balance interoperability with existing IPv4 infrastructure, scalability for future growth, and compatibility with IP address-embedded applications. Structured into three key sections, the chapter first explores development trends shaping IPv6 deployment, evaluates technical challenges like network security and scalability, and proposes a strategic migration plan. The roadmap prioritizes seamless integration across operating systems and applications, ensuring service continuity during the transition.
