The "study based on IPv6 domain name stem server technology", an important subject for knowledge innovation of the Chinese Academy of Sciences, undertaken by the CNNIC has passed the approval and acceptance of the experts team the other day. The result has indicated that China has already mastered the key technology for setting up, operating, maintaining and guaranteeing the domain name stem server for the next generation Internet. This has made China possible to provide a strong technological support to the large-scale disposition of the IPv6 network in providing the basic name service.

The domain name system is the basic service for the Internet while the stem server is even more the foundation of the whole domain name system. In the strategic point of view for national informationization this is a strategically fundamental service having things to do with the all-round situation of the country. The Chinese government has invested heavily for the construction of next generation in China. The popularization and disposition of the IPv6 network will entail an adjustment of the stem server under the IPv6 domain names, thereby making a breakthrough of the situation in which the stem server is monopolized by only few countries.

As learned at present there are only 13 domain name stem servers for the Internet service and they are mainly managed by the USA, Japan and Britain while China has no domain name stem server of its own. The disposition will incur such problems to happen as information safety, analytical velocity and flows out of the country when making users domain name checkup and inquiries. If China can set up its own IPv6 stem server it will bring about an impact of great importance on the information security in China.

According to the introduction the experimental system of the IPv6 stem server project China constructed has already entered into service, and through the IPv6 testing network it is able to receive more than 10,000 times of checkup and inquiries from all over the world. The test has proved that the system is able to provide a safe and reliable domain name stem server system, support the newly-boomed ways for site searching and inquiry into a great number of domain names, including those in Chinese, ENUM and universal websites. The result has reached the international advanced standard on the whole. That is to say, it is at the world advanced level in multi-lingual domain names (domain name in Chinese), key-word websites (universal websites). He suggested that the CNNIC grasp the opportunity in the development of the IPv6 network for improving the result of the IPv6 domain name stem server so as to popularize its influence in the world, striving for China's international status in the field of the IPv6 network.

To use the IPv6 technology for the construction of the next generation Internet is a mega-trend, introduced Mao Wei, Director of the CNNIC. And by grasping the opportunity China will be able to hold a more important position in the next generation Internet and to get more rights to speak and lay its hands on it. As an administrative organ for the registration of domain names in China, it is under the very circumstances that the CNNIC has paid great attention to the researching and solving the establishment, operation, maintenance of the key technology for guaranteeing the safety of the IPv6 domain name stem server system.

The big breakthrough scored by China in the domain name stem server for the next generation Internet will also be good for the application and establishment of the IPv6 domain name stem server in future, experts hold.
