国际化域名 (IDN) 服务

注:所有语种版本中,英文版为官方版本,其他语种版本仅供参考.

国际化域名 (IDN) 服务允许注册管理运行机构通过向 ICANN 组织提交服务请求,添加、修改或删除其在通用顶级域 (gTLD) 中使用的各种语言和文字。IDN 服务流程采用预批准的标准《注册管理机构协议》(RA) 修订案文件,帮助简化处理过程。

下面提供了有关如何提交 IDN 服务请求的一般说明。为使 ICANN 组织能够高效审核 IDN 服务请求,注册管理运行机构应将标签生成规则 (LGR) 参考列表中提供的解决方案包含到其提交的 IDN 列表中,因为这些 LGR 已经通过了安全性和稳定性审核。此外,ICANN 还开发了一个 IDN 列表审核工具,通过该工具,注册管理运行机构可以轻松地将其 IDN 列表与相关的 LGR 参考列表进行比较。

添加、修改或删除 IDN 服务

如果《注册管理机构协议》(RA) 附件 A 中涉及 IDN 服务,则注册管理运行机构可以提供国际化域名 (IDN)。ICANN 组织制定了 IDN 服务请求流程,通过该流程,gTLD 注册管理运行机构可以请求在其 RA 中添加、修改或删除 IDN 服务(如已使用的语言和文字)。下面的步骤主要说明了用于发起 IDN 服务请求的流程,这些步骤遵循注册管理机构服务评估政策 (RSEP)。

第一步:在域名服务门户中提交"IDN 服务 - 添加、修改或删除"请求

按照相应步骤 (a) 确认请求类型,(b) 提供所有相关的 IDN 列表和补充详细信息,(c) 阐明对 IDN 服务所做的更改可能引发的任何安全性、稳定性或竞争问题以及是否会影响当前已注册的域名,(d) 提供签署人信息(有权对 RA 进行修订的联系人)。

第二步:ICANN 审核

ICANN 对请求进行审核以确保提交的信息完整全面,并对拟定服务请求进行审核以确定是否需要提醒注册管理运行机构注意可能会引发的重大安全性、稳定性或竞争问题。

第三步:裁定和最终处理

批准请求后,ICANN 组织将启动授权流程(执行 RA 修订案,或发送一封"自由部署"函件),并且 ICANN 将与 IANA 一起推进 IDN 列表更新。

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."
