假冒ICANN域名认证书

本页面还提供其他语种:

ICANN注意到,一些在线实体正在尝试销售假冒"认证书",并声称这些授权书是用以保护通用顶级域名的必需品。这类欺诈人员威胁注册人必须购买这一保护服务,从而从注册人处获得资金。这类"认证书"制作精良,并在未经授权的情况下盗用了ICANN的标志。

请注意:ICANN并不向注册人发放认证书,且并不直接从注册人处收取费用。

ICANN目前正在调查这类案件,并建议碰到类似情况的注册人立即通过以下邮件地址向ICANN的合同合规部门汇报:compliance@icann.org

ICANN建议,任何希望注册通用顶级域名下级域名的个人或法律实体应当通过一名ICANN授权注册商进行注册。如需更多信息,包括当前ICANN授权注册商的清单,请点击此处:https://www.icann.org/resources/pages/registrars-2012-02-25-zh

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。如果缺乏这样的协调,我们全球统一的互联网也将不复存在。ICANN成立于1998年。它是一家非营利性的公益型企业,其参与人员来自全球各地,均致力于确保互联网的安全性、稳定性和互用性。旨在促进互联网唯一标识符之间的竞争,并为其制定政策。ICANN不负责互联网的内容管理。无法阻止垃圾邮件,也并不负责处理互联网的接入事务。但该组织通过对互联网域名系统的协调,对互联网的发展和演进有着重要的影响。如需了解更多信息,请参见:www.icann.org

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."
