洛杉矶——2020 年 4 月 30 日——互联网名称与数字地址分配机构 (Internet Corporation for Assigned Names and Numbers, ICANN) 于今天宣布其附属机构公共技术标识符 (Public Technical Identifiers, PTI) 现诚邀社群与互联网号码分配机构 (Internet Assigned Numbers Authority, IANA) 的员工和 PTI 董事会成员进行交流,讨论 PTI 的首份全面战略规划的编制工作。

当 PTI 董事会和 IANA 员工参加 ICANN66 届加拿大蒙特利尔会议之时,他们与大家分享了首份战略规划的发布时间线,其中还谈及需要在 ICANN67 届墨西哥坎昆会议中展开面对面的交流。鉴于"2019 冠状病毒病 (COVID-19)"的疫情爆发,且会议被更改为仅采取远程方式召开,我们继而调整了方案,现将在本轮公共评议期(即从 2020 年 4 月 20 日至 6 月 1 日期间)召开期间举办两场互动式网络研讨会。

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。

公共技术标识符 (PTI) 简介

公共技术标识符 (Public Technical Identifiers, PTI) 是一家 ICANN 的附属机构,负责执行互联网号码分配机构 (IANA) 的职能,具体包括:管理支持互联网运营的域名系统 (DNS) 根区、全球 IP 地址空间和其他协议参数。在 IANA 职能管理权顺利移交给多利益相关方社群后,PTI 于 2016 年应运而生。PTI 负责根据与 ICANN 签署的合同执行 IANA 的职能。

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."
