This article introduces a way to realize dynamic address size in IPV6 datagram. In the improved datagram, only 64 bits address size is fixed other than 128 bits in IPV6, and an optional extension address header is attached after base header.

• 介绍了在IPV6中实现动态地址长度的方案 ；在改进后的IPV6数据报中仅有 6 4位地址是固定的 ；超过 6 4位的地址形成一个单独的头部 ；此可选的扩展地址头部紧排在IPV6数据报基本头部之后 .
