IANA 管理权移交实施

IANA 管理权移交和加强 ICANN 问责制所需的实施工作已完成。该页面提供了实施阶段中编制的文件和材料的链接。请点击以下链接获取更多信息。

根据 IANA 管理权移交协调小组 (ICG) 和加强 ICANN 问责制跨社群工作组(问责制 CCWG)提出的提案,ICANN 确定了为开展 IANA 管理权移交而必须完成的工作。这些工作被划分为 3 个不同的路线。下图显示了 ICANN 和社群工作的状态。


  1. 根区管理工作路线包含取消 NTIA 授权流程的根区管理系统 (RZMS) 变更、生成 RZMS 和平行测试 RZMS 的平行测试,以及制定和与根区维护人 Verisign 签署协议方面的相关项目。
  2. 管理权移交工作路线包括编制与运营社群的关系文档、成立移交后的 IANA (PTI) 实体、建立客户常任委员会 (CSC) 和根区发展审核委员会 (RZERC) 以及实施 IANA 客户服务升级机制和服务水平协议 SLA 方面的相关项目。
  3. 加强问责制工作路线包含实施 ICANN 独立审核和重审请求流程的改进措施、更新 ICANN 的管理文件以及实施问责制 CCWG 定义的新社群权力方面的相关项目。





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."
