Version 6 of the Internet Protocol Version 5 was allocated to the experimental Internet Stream Protocol (RFC 1190) 5+ years old Poised for the continued growth and success of the Internet IPv6 address is 128 bits 2000:910A:2222:5498:8475:1111:3900:2020 IPv4 vs. IPv6 … a longer term solution  IP next generation (IPng) 1991: Work starts on next generation Internet protocols More than 6 different proposals were developed 1993: IETF forms IPng Directorate To select the new protocol by consensus 1995: IPv6 selected Evolutionary (not revolutionary) step from IPv4 1996: 6Bone started 1998: IPv6 standardized Today: Initial Commercial products and deployments A Standard Environment Networks of “WEB present” wireless devices IPv6 Enabled Picture Frame Digital Picture rame Features Plug Play 640 x 480 VGA JPEG Image Format Storage: 10 photos/250 on-line IPv6時代來臨 IPv6 勢將取代 IPv4，且其時代已經來臨 IPv6 相關技術標準制訂工作皆已完成 寬頻及無限通訊技術急速發展，將加速IPv4用罄。 IPv6 將是Internet 新應用及商業的契機 IPv6 之設計已考量未來 Internet 可能之需求，故可配合各項新的應用，帶來新的商機。 IA 及Wireless 應用。 各先進國家積極投入研發與推廣 各先進國家多已投入大量經費與人力從事研發與推廣，以因應IPv6 時代提早來臨，日本及韓國更將其訂為國家政策。 IPv6 國際發展現況 IPv6國際發展現況 - IPv6 標準現況 IPv6國際發展現況 - IPv6 建置現況 IPv6國際發展現況 - IPv6產品發展現況 IPv6國際發展現況 - IPv6位址分配現況 IPv6國際發展現況 – 日本發展現況 IPv6國際發展現況 – 日本發展現況 JAPAN -- IPv6 Council Initiated by Ministry of Public Management, Home Affairs, Posts and Telecommunications Chair: Jun Murai Not only router vendors and service providers, but home appliance developers etc. are involved TAO (Telecommunications Advancement Organization of Japan) conducts a nation-wide IPv6 experiment including home appliance application development, using budget of 8 billion Yen (= $ 800k).
