白俄罗斯共和国的IDN ccTLD申请顺利通过字符串审核

ICANN非常高兴地宣布白俄罗斯共和国对拟定IDN ccTLD的申请现已通过字符串审核流程。


ICANN董事会于2009年10月30日在韩国首尔宣布通过《IDN(国际化域名)ccTLD快速通道流程》。首批申请自2009年11月16日起开始接收。该流程使得国家和地区可向ICANN提交有关IDN ccTLD的申请,使用非拉丁字母的文字来代表相应国家或地区名称。IDN ccTLD申请必须满足以下几个要求:

  • 代表IDN ccTLD的文字必须为非拉丁字母文字;
  • 代表该IDN ccTLD的语言必须为该国或该地区的官方语言;和
  • 必须满足一套特殊技术要求(由一批DNS和IDN专家构成的外部DNS稳定性专家小组对技术要求进行审核)。


  • 筹备阶段(该国/地区的申请人的筹备工作):必须扩大对拟定IDN ccTLD申请的社群意识;告知社群谁将运营该顶级域名,以及运营方案如何;准备和搜集所有必要支持文件。各类申请及支持本流程的其他材料则通过一套在线系统提交,该系统链接为:
  • 字符串评估:按照上述IDN ccTLD字符串的标准,所有申请均将接受技术和语言要求的审核。
  • 字符串授权:成功满足字符串审核标准的申请将获得申请授权的资格。申请流程与以ASCII字符为基础的ccTLD的ICANN IANA申请流程相同。申请人须将字符串授权申请提交至IANA根域管理

包括本公告在内,目前已有34个国家/地区申请成功通过了字符串的审核。其中26个国家/地区(代表着36个IDN ccTLD)已经获得在域名系统根域中的授权;余下部分目前分别处在申请筹备阶段、正式申请阶段或字符串授权阶段。IDN快速通道项目的最新动态将随时在"快速通道流程"网页上发布:

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"""" is not an IDN."
