ConclusionConclusion

▣ New challenges for Next Generation Internet in Korea◈ More than 20 million users of Internet (50% of population)◈ Emerging Internet areas

IMT-2000Home NetworkEtc.

▣ IPv6 will be core technology for next-generation Internet.

▣ It is not too early to begin planning for IPv6 use in your country.

▣ Korea will contribute to the deployment of IPv6 in the Asia-Pacific region, as well as worldwide.
