中文摘要：

对下一代网络的核心技术IPv6进行了分析，讨论了IPv6的特点和优势，在IPv6中，所有的零和所有的数字对于任何领域都是合法的，特别定义的除外，前缀可以包含零值字段或以零结尾。所有类型的IPv6地址都被指派给接口而不是节点，一个IPv6单播地址对应一个接口，每一个接口属于单一的一个节点。那些节点接口单播地址中的任何一个都可以用来作为对这个节点的一个标识。IPv6将会在下一代网络中扮演一个重要角色，论述了IPv6在我国的发展现状和重要意义。

英文摘要：

Discussing IPv6, the kernel technology in the next generation network, and its ongoing development, its importance as well as its characteristics and merits. In IPv6, all zeros and all other numbers are legal values for any field, unless specifically excluded. Prefixes may contain zero-valued fields or end in zeros. All types of IPv6 addresses are assigned to interfaces rather than nodes. An IPv6 unicast address refers to a single interface. Each interface belongs to a single node, any of whose interfaces unicast addresses may be used as an identifier for the node. IPv6 will act a major role in the next generation network.
