ICANN 发布最新域名市场指标


洛杉矶——2019 年 12 月 9 日——互联网名称与数字地址分配机构 (Internet Corporation for Assigned Names and Numbers, lCANN) 于今天宣布发布最新行业衡量标准,作为"域名市场指标 (Domain Name Marketplace Indicators)"项目的组成部分。该项目代表着与通用顶级域 (generic top-level domains, gTLD) 和国家和地区顶级域 (country code top-level domains, ccTLD) 相关的统计数据,从而在域名市场发展过程中针对可信信息提高透明度。



  • 强健竞争:注册人选择、注册人域名采用、服务提供商的市场准入、服务提供商的竞争。
  • 市场稳定:服务提供商的合同合规。
  • 信任:行业保护措施。

ICANN 计划继续扩大本项目下有限指标的覆盖范围,每年发布两次这类统计数据,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。

一支社群顾问小组将与 ICANN 开展合作,识别构成当前项目的相关指标。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 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"""" is not an IDN."
