集中化域资料服务 (CZDS)

注:所有语种版本中,英文版为官方版本,其他语种版本仅供参考.

集中化域资料服务为利益相关方提供了一个请求访问参与的顶级域注册管理机构提供的域文件的集中点。该服务是在数百个新 gTLD 增加到互联网中时升级区资料传输的解决方案。

要求每个新 gTLD 注册管理机构在其 gTLD 的技术授权时向批准的请求方(如执法人员、知识产权律师、研究员)提供域资料。

一旦签署了 gTLD 注册管理机构协议,将向新注册管理机构提供使用集中化域资料服务的说明。

CZDS 为注册管理机构带来的好处

  • CZDS 简化了签订域资料合同的流程。注册管理机构可以仅单击一下鼠标来批准或否决请求,而无需为每个请求都制作和签署合同。
  • 通过指定 ICANN(而不是使用内部资源)处理域资料文件传输 (AXFR)、设定格式并分发给批准的最终用户,注册管理机构可以节省更多时间。

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."
