超过500个新gTLD现已引入互联网

互联网名称与数字地址分配机构(ICANN)今日宣布,已获授权的新通用顶级域名(gTLD)数量目前已经超过500个。通用顶级域名".NTT"(日本电信电话株式会社)是第500个获得授权的新gTLD。现在,几乎每天都有一个新域名获得授权。

新gTLD项目是互联网史上经历的最大规模的扩张活动。接下来几年间,将会有成百个新顶级域名或"字符串"进入互联网。2014年10月23日,首批四个字符串获得授权。自那以后,本项目一直致力于改进工作、促进竞争、创新和消费者选择。

请踊跃参加我们在新加坡召开的 新gTLD项目会议:状态、审核和后续轮次。熟悉新里程碑事件和申请截止日期,以帮助注册局及时获得授权。本节会议还将探讨本项目启动后续轮次的规划。

我们期待着各界人士积极参与进来。敬请访问 项目审核页面 ,就新gTLD项目建言献策。

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."
