剩余IPv4地址将被再分配给地区互联网注册局 | 地址再分配意味着IPv4已近枯竭

ICANN于今日宣布启动向五大地区互联网注册局(RIR)分配剩余互联网协议第4版(IPv4)地址资源的流程。这一流程的启动是因为 拉丁美洲和加勒比海地区互联网地址注册局(LACNIC)的地址供应量已经不足800万个。

这意味着IPv4地址的全球供应量已经接近一个关键水平。随着越来越多的设备上网,IP地址的需求也日益增多,而IPv4却无法提供足够的地址以满足这一扩张需求。ICANN鼓励全球网络运营商部署IPv6,使得互联网得以快速发展。

ICANN IANA和技术运营副总裁伊莉斯·格里琪(Elise Gerich)指出:"随着尚未分配的IPv4地址日益枯竭,我们从RIR那里获得许多指导,对此我们表示衷心感谢。"我们此次对少量IPv4地址进行再分配,以确保每个地区均能获得相同数目的地址,并同时与社群合作继续推进对IPv6的支持。"

鉴于 拉丁美洲和加勒比海地区互联网地址注册局(LACNIC) 的供应量严重下滑,则五大RIR的政策制定社群共同制定了一项政策,帮助ICANN平均再分配这些地址资源。这就是IPv4资源枯竭后分配机制的全球政策中分配部分所描述的内容。

ICANN卓越运营经理雷欧·弗格达(Leo Vegoda)指出:"今天早些时候,IANA中已恢复的IPv4地址空间注册局下约拥有2000万个IPv4地址,而现在的规模却不到这一数据的一半。""对日益减少的IPv4地址空间进行再分配并不是促进互联网发展的可持续性方式。任何网络如想继续生存下去就必须部署IPv6。"

IPv6可提供3.4×1038个独一无二的地址,能够满足互联网的几何级数式增长,而IPv4仅能提供37亿个地址。

格里琪还指出:"为了继续推动互联网带来的经济发展和机遇,我们必须尽快采用IPv6,维持这一增长趋势。"

Domain Name System
Internationalized Domain Name ,IDN,"IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet ""a-z"". An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese. Many languages also use other types of digits than the European ""0-9"". The basic Latin alphabet together with the European-Arabic digits are, for the purpose of domain names, termed ""ASCII characters"" (ASCII = American Standard Code for Information Interchange). These are also included in the broader range of ""Unicode characters"" that provides the basis for IDNs. The ""hostname rule"" requires that all domain names of the type under consideration here are stored in the DNS using only the ASCII characters listed above, with the one further addition of the hyphen ""-"". The Unicode form of an IDN therefore requires special encoding before it is entered into the DNS. The following terminology is used when distinguishing between these forms: A domain name consists of a series of ""labels"" (separated by ""dots""). The ASCII form of an IDN label is termed an ""A-label"". All operations defined in the DNS protocol use A-labels exclusively. The Unicode form, which a user expects to be displayed, is termed a ""U-label"". The difference may be illustrated with the Hindi word for ""test"" — परीका — appearing here as a U-label would (in the Devanagari script). A special form of ""ASCII compatible encoding"" (abbreviated ACE) is applied to this to produce the corresponding A-label: xn--11b5bs1di. A domain name that only includes ASCII letters, digits, and hyphens is termed an ""LDH label"". Although the definitions of A-labels and LDH-labels overlap, a name consisting exclusively of LDH labels, such as""icann.org"" is not an IDN."
