IPv6 is short for "Internet Protocol Version 6". IPv6 is the "next generation" protocol designed by the IETF to(71) the current version Internet Protocol, IP version 4("IPv4").
Most of today’s internet uses IPv4, which is now more than twenty years old. IPv4 has been(72) resilient in spite of its age, but it is beginning to have problems. Most importantly, there is a growing(73) 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(74) number of available IPv4 addresses. It also adds many improvements to IPv4 in areas such as routing and network autoconfiguration. IPv6 is expected to gradually replace IPv4, with the two coexisting for a number of years during a transition(75) .
选项
A、days
B、period
C、phase
D、epoch
答案
B
解析
IPv6是“互联网协议第6版”的简称,它是由IETF设计的下一代互联网协议,目的是取代(replace)现有的互联网协议第4版(IPv4)。目前,大多数互联网使用的IPv4已经有了20多年的历史。虽然IPv4在过去的应用中具有不同寻常的(remarkably)业绩,但是现在看来已经暴露出很多缺点。最为重要的是,现在的互联网(IPv4)已经面临地址短缺(shortage)的问题,而这正是所有新加入互联网的计算机所迫切需要的。IPv6能够解决IPv4存在的诸如有效网络地址受限(limited)等问题,同时还对IPv4做了大量的改进,包括路由和网络自动配置等。IPv6和IPv4将在过渡期(period)内共存几年,以后IPv6将渐渐取代IPv4。
