报告域名冲突

当尝试对私营域名空间(例如:在非授权顶级域名或简短的不合格域名)的一个域名进行解析时,却导致了对公共域名系统 (DNS) 的查询,此时即发生了域名冲突事件。当私营和公共域名空间的管理界限出现重叠时,域名解析就可能导致意外的或是有害的后果。

域名冲突并不是一个新问题。向域名系统中引入任何新的域名,不论是通用顶级域名、国家和地区代码顶级域名或是二级域名 (SLD),都有可能造成潜在的域名冲突。构建一个安全、稳定和富有弹性的互联网是 ICANN 的首要任务。因此,我们向互联网社群做出承诺,将启动一项实质性的工作来缓解和管理域名冲突事件。

如果您的系统因域名冲突事件而明显遭受到严重影响,请填写下面的表格来报告这一事件。

ICANN 仅会在如下场景中启动域名冲突报告的应急响应:有理由相信域名冲突会对人类生活造成迫切的危险。

应急响应可能包括暂时移除受影响的二级域名或从域名系统移除整个顶级域名。ICANN 将做为初始报告点,并在必要时与相关注册局运营商进行协调,以确保对该报告的内容尽快采取行动。ICANN 下属的签署了协议的注册局运营商应在从 ICANN 收到请求的 2 个小时内采取措施。

如果您认为您的域名冲突符合上述标准(即您的系统因域名冲突事件而明显遭受到严重影响,或者您有理由相信该域名冲突对人类生活造成了迫切危险),请使用下面的表格将您的报告提交给 ICANN。

提交报告后,请查看《供 IT 专业人士使用的域名冲突识别与缓解指南》(版本:1.1) [PDF, 799 KB] 以获取更多信息。

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."
