IPv6 Architecture and Deployment by Richard Johnson

"IPv6 Architecture and Deployment"

"IPv6 Architecture and Deployment" is a comprehensive guide that addresses the urgent need for next-generation Internet protocols amid the limitations and exhaustion of IPv4. Beginning with the fundamental rationale for IPv6 and the paradigm shift it represents, this book carefully explores the evolution of the protocol, outlines the distinguishing architectural features between IPv4 and IPv6, and delves into the motivations and challenges behind widespread adoption. Readers are provided with a thorough understanding of IPv6 design principles, industry standards, and the drivers influencing global deployment amidst technical, economic, and organizational complexities.

The book moves systematically through the core components of IPv6, offering deep insights into addressing architectures, protocol operation, routing extensions, and network co-existence mechanisms. Detailed chapters examine critical topics such as stateless and stateful address assignment, extension headers, advanced routing protocols, security architecture, and operational best practices. Special attention is given to transition mechanisms—including dual stack, tunneling, and translation strategies—helping practitioners navigate the complexities of phased deployments and the eventual shift to IPv6-only networks. Furthermore, the text provides actionable guidance on managing, automating, and monitoring IPv6 networks at scale, ensuring reliability, security, and performance.

Practical deployment scenarios are illustrated across diverse environments, from enterprise and carrier-grade networks to cloud, IoT, edge computing, and research testbeds. With dedicated sections on contemporary innovations—such as segment routing, zero-trust frameworks, and IPv6's role in 5G and beyond—the book positions readers to anticipate future trends and leverage IPv6 for advanced programmability, security, and scalability. "IPv6 Architecture and Deployment" stands as an essential resource for IT professionals, architects, network engineers, and students seeking authoritative knowledge and strategic insight into the successful implementation of IPv6 in modern infrastructures.
