注册局和注册商WHOIS服务澄清事项

ICANN现公开发布对ICANN协议中WHOIS规格的澄清事项。

为了支持注册局和注册商对政策的推行,方便其遵守各项规格要求,ICANN现发布对《注册数据目录服务》(RDDS)(即人们熟知的WHOIS服务)的澄清事项。本次澄清事项的发布旨在回应注册局和注册商就RDDS规格所提出的问题,并支持签约方遵守《注册局协议》(RA)和《注册商授权协议》(RAA)。

本文题为《对<新gTLD注册局协议>规格4、<2013注册商授权协议>(RAA)、<注册数据目录服务(WHOIS)规格>的澄清》,现发布于以下链接:https://www.icann.org/resources/pages/advisories-2012-02-25-en

大部分澄清事项同时适用于注册局和注册商;但澄清事项的第二部分则仅适用于注册局,第三部分仅适用于注册商。ICANN注意到在现有系统中推行这些澄清事项需要一定时间,因而通告各方应自2015年2月12日起推行这些政策。发布这些澄清事项的目的之一是确保能够方便地剖析结果。现鼓励感兴趣的用户在开发RDDS成果剖析器时考虑这些澄清事项。

公告含有37项澄清事宜,其中一些为必须遵守项目,其他则为可选项目。本文包含,但不仅限于对以下内容的澄清:格式规则、字段定义、服务水平要求、预授权测试规格。

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."
