洛杉矶——2019 年 4 月 17 日——互联网名称与数字地址分配机构 (Internet Corporation for Names and Numbers, ICANN) 于今天宣布出版第一版《域名市场指标》(Domain Name Marketplace Indicators) 报告,其中囊括了通用顶级域 (gTLD) 和国家和地区顶级域 (ccTLD) 的统计数据。

这份报告是此前发布的《gTLD 市场健康指数》(gTLD Marketplace Health Index)(试用版)的改进版本。《gTLD 市场健康指数》报告则首先在 2016 年 7 月发布,后又于 2018 年 6 月在年度报告中发布。本轮报告扩大了数据范围,囊括了 ccTLD 的数据。ICANN 计划扩大有限指标的数据范围,并计划每两年发布一次这类统计数据,用于跟踪目标实现进度,即支持域名市场强健、稳定和可靠的发展。

由社群成员构成的顾问小组与 ICANN 展开合作,在筹备发布这份报告期间,修正了这类指标。在发布市场指标 1.0 版的同时,ICANN 组织还将继续与社群和顾问小组合作,评估可能在未来被纳入本项目的其他的改进措施。

ICANN 简介

ICANN 的使命在于确保全球互联网的稳定、安全与统一。在互联网上寻找另一个人的信息,您必须在您的电脑或其他设备中键入一个地址——可以是一个名称或是一串数字。这一地址必须是独一无二的,只有这样电脑之间才能互相识别。ICANN 则负责协调这些分布在全球各地的唯一标识符。ICANN 成立于 1998 年,是一家非营利公益型企业,其社群成员遍布全球各地。

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."
