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.

集中化域资料服务可为利益相关方提供一个集中化平台,以请求由参与的顶级域注册管理机构提供的域文件的访问权限。当数以百计的新通用顶级域 (NgTLD) 添加到互联网时,这项服务用于扩展域资料传输功能。

每个 NgTLD 注册管理机构需凭借其 gTLD 的技术授权能力,向已获批准的请求方(例如,执法机构、知识产权律师、研究人员)提供域资料。

一旦签署了《gTLD 注册管理机构协议》,新注册管理机构将会获得有关利用集中化域资料服务的指导说明。

面向最终用户的 CZDS

面向注册管理机构的 CZDS

  • CZDS 可简化域资料合同的签署过程。通过 CZDS,注册管理机构只要执行一次点击操作即可批准或拒绝多项请求,无需为每项请求创建并签署合同。
  • 此外,注册管理机构还可以委托 ICANN 传输域资料文件 (AXFR)、对域资料文件进行格式调整以及将其发送至已获批准的最终用户,这样不仅可以节省内部资源,还可以节省更多时间。

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."
