提案征询:通用顶级域 (gTLD) 市场健康指数评估

互联网名称与数字地址分配机构 (Internet Corporation for Assigned Names and Numbers, ICANN) 现征询一家或多家合格提供商,用以 (a) 评估域名系统(Domain Name System, DNS) 的拟定框架,(b) 对最终建议指标进行详细分类,和 (c) 确定 ICANN 组织外部的任何必需数据的来源。

通用顶级域 (gTLD) 市场健康指数的确定旨在促进 ICANN 实现战略目标 (2.3),即"支持 gTLD 市场朝着健康、稳定和可信的方向发展。"这项计划的结论将有利于在域名市场中提高可信数据的透明度。

本轮评估预计将在 2018 年 1 月 15 日到 2018 年 3 月 30 日期间进行。

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."
