说明 / 背景: 有一个专门的 公众意见页面 ,用于收集您对《申请人指导手册草案》(第 4 版)以及相关支持文档的意见。该指导手册用于介绍申请新通用顶级域名(新 gTLD )的过程。

在这个专用页面上,您会看到《申请人指导手册草案》(第 4 版)的完整版本,及其 6 个独立模块。根据您感兴趣的领域,您可以对整个指导手册添加评论,也可以按模块进行评论。此外,在每个模块的讨论区域下,您还会发现一个文件列表,这些文件是针对该特定主题的解释性备忘录或报告。这一系列的支持文件旨在用于帮助理解此项计划的实施工作。这些文件中添加了红线和注解,可以方便您了解《申请人指导手册草案》从第 3 版到第 4 版的演进中做了哪些更改。

ICANN 期望通过这一讨论过程与互联网社区进行一次富有成效的对话。

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."
