准备好,迎接下一代互联网

你对这一代互联网还不满意?那么,准备好,新一代网络它来了我们正在使用的互联网是在IPv4协议的基础上运行的,而IPv6是下一版本的互联网协议。目前,随着互联网的迅速发展,可以预见地,IPv4定义的有限地址空间将被耗尽,地址空间的不足必将影响互联网的进一步发展。为了扩大地址空间,拟通过IPv6重新定义地址空间。IPv4采用32位地址长度,只有大约43亿个地址,估计在2005～2010年间将被分配完毕,而IPv6采用128位地址长度,几乎可以不受限制地提供地址。按保守方法估算IPv6实际可分配的地址,整个地球每平方米面积上可分配1000多个地址。在IPv6…

Preparing to welcome IPv6

IPv6 is the "next generation" protocol to replace the current version Internet Protocol, IP Version 4 ("IPv4"). Most of today's internet uses IPv4, which is now nearly twenty years old. IPv4 has been remarkably resilient in spite of its age, but it is beginning to have problems. Most importantly, there is a growing short- age of IPv4 addresses, which are needed by all new machines added to the Internet. IPv6 fixes a number of problems in IPv4, such as the limited number of available IPv4 addresses. It also adds many improvements to IPv4 in areas .
