IPv6 offers important business and technical advantages. While all/most existing IPv4-based infrastructures will continue to work after the last IPv4 address

39、troduction When IPv4 emerged as the standard Internet protocol in the 1980s for the “Internet“, the address space - some four billion IP addresses - seemed more than adequate. Today it is clearly no longer the case. The world has moved from IP enabled to IP dependent. As of 2015 more than 83 percent

40、 of the worlds population no longer has access to a “public Internet address.“ In North America, Latin America, Asia, and Europe, the IPv4 address pool is already entirely depleted. With the growing number of users and the proliferation of smart devices and things, IPv4 address space exhaustion is a

41、 major Information and Communications Technology (ICT) issue. The current IPv4-based Internet can no longer sustain the explosive growth of ICT. Any organization that relies on the Internet to any extent needs to be prepared to support IPv6. IPv6 needs to be adopted globally across all parts of the

42、Internet ecosystem. Global service providers and mobile operators are already deploying IPv6 in order to keep the Internet growing. IPv6 is allowing them to continue to grow their businesses and deliver the services that all of todays e-commerce is based on. The move to IPv6 is inevitable, there is

43、no alternative plan at this time. IPv6 is the cornerstone of our connected society. IPv6 offers important business and technical advantages. Among them: higher performance, enhanced mobility, automated management, built-in multicasting for multimedia applications, enhanced security, simplified admin

44、istration and many more. Indeed, many enterprises have already determined that IPv6 is a much better networking tool than its predecessor, and it offers much greater capabilities for future technologies developed for networking platforms. Because all/most existing IPv4-based infrastructures will con

45、tinue to work after the last IPv4 address is issued, enterprises may be tempted to put off transitioning to IPv6 till some later date. Postponing the inevitable, however, can put an enterprise at a competitive disadvantage. As more and more customers operate in an IPv6 world, companies supporting on

46、ly IPv4 risk being shut out of high-growth markets because they are unable to reach, or be reached by, these customers. The fallacy in this position is that maintaining IPv4-only communications can put enterprises at a competitive disadvantage. Seamless, pervasive connectivity is an integral part of

47、 doing business today. IPv6 enables the enterprise and the global Internet to keep growing in a secure and open manner, and to scale toward the demand of new applications and, literally, billions of connected devices, while streamlining operations and provisioning. Enterprises deploying IPv6-enabled

48、 services are in a better position to capture the market changes, be more competitive, increase their growth potential, and provide for improved business continuity. ETSI ETSI GR IP6 001 V1.1.1 (2017-06) 8 Of particular note is the fact that regardless of an organizations IPv6 preference, its custom

49、er base is currently deploying it. As consumers and customers adopt IPv6, enterprises will need to ensure that their own technology assets align with how their customers prefer to do business. As the shift to online shopping has already shown, customers will continue to buy from companies that do business on their terms. Meeting the needs of the customer base (many of which already have an IPv6-connected device) should be an imperative for all organizations. Today, enterprises should already have
