IPv4地址即将告罄 全球加速进入IPv6时代

随着全球IPv4地址即将在“未来几个星期内”用尽,业内普遍认为,IPv4地址的提前告罄将加速IPv6的发展,IPv6是目前唯一能解决IP地址短缺的可行途径。

从去年开始,电信运营商中国电信和中国移动已经启动了IPv6的试点工作。

“互联网之父”文顿·瑟夫目前是美国谷歌公司副总裁兼首席互联网顾问,他在1977年创建互联网通信协议“IPv4”,让全球电脑可以互相连线。而IP地址是分配给每台电脑、网站或其他联网设备的一系列号码,每个IP地址都是独一无二的。

此前,互联网名称与数字地址分配机构(ICANN)曾预计,IPv4地址会在2011年8月耗尽。对此有专家认为,如今世界各国对于物联网发展的强调,以及各种智能终端的普及是IPv4地址加速枯竭的重要原因,而唯一的解决途径是更换新一代IP协议:IPv6。

上海证券分析师张涛表示,以目前国内的电脑和手机用户保有量来看,IPv4还可以支撑,但随着物联网对于网络要求的提高,IPv4地址显然已经不够,发展IPv6也可以认为是为未来物联网的发展进行必要的网络准备。

而世界范围内由IPv4向IPv6的协议转型已经启动。据悉,自格林尼治时间2011年6月8日零时1分开始的24小时将是IPv6协议系统的第一个试用日。届时,网络搜索引擎谷歌公司和社交网站“脸谱”(Facebook)等网站将率先启动IPv6协议系统,为用户及工程师提供测试和分析平台。

而自去年,中国电信和中国移动已经开始个别地区的IPv6试点工作,包括IPv6协议互通、基地建设及网络管理等方面的测试。

华创证券分析师刘洪军表示,从目前趋势来看,IP地址提前枯竭将加速IPv4向IPv6协议的转换,进而加速电信运营商、企业和政府局域网将现有的路由器和以太网交换机,替换成支持IPv6的新品。目前国内上市公司中兴通讯和星网锐捷有提供相关设备。
