This book starts from introducing the occurrence and current situation of problems in IPv4, and elaborates on all aspects of IPv6, including IPv6 addressing structure, extension headers, authentication and security, support for any on-demand and multicast, and support for related protocols. Impact, and also discusses the strategies and applications of IPv4 to IPv6 transition. The content of this book is from shallow to deep, and the language is concise and easy to understand. It provides a clear and distinctive introduction to IPv6 for experienced network administrators and researchers to adapt to IP upgrade changes.
