关于 ccTLD 合规


ICANN 没有针对 ccTLD 运营商采取合规措施的合同权限。

尽管 ICANN 已经同 ccTLD 方面签署超过 50 个问责制框架和往来信件以及一定数量的赞助协议和谅解备忘录,但是这些文件仅仅是为了记录 ccTLD 管理机构和 ICANN 之间很少的责任分工和范围。

对于 ccTLD 方面而言,这包括承诺遵守相关技术标准。对于 ICANN 则是要同 ccTLD 运营商合作,解决关系到双方共同利益的技术问题,以确保互联网的安全、稳定和正常运行。

ccTLD 在注册、注册服务商委任和 Whois 方面的政策按照国内相关的监管机制进行管理,ICANN 的合规部门不会介入这些方面。

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"""" is not an IDN."
