当一个域名到期后,根据注册服务机构所提供的方案,该域名可能会进入一个可长达 45 日的自动续订宽限期。根据注册服务机构的政策,注册服务机构在这一期限结束后,可能会将域名从数据库中删除。

在一家注册服务机构删除一个到期域名前,该机构必须中断这个域名的解析路径。这意味着与该域名相关的所有服务(例如网页和电子邮件服务)可能已经暂停工作。这将警告您该域名已经到期,必须进行续订。如需了解如何进行域名续订,请访问 ICANN 网站中关于续订域名的页面。


如果您与您的注册服务机构在续订费用支付方面产生了争议,请访问 ICANN 网站中的关于已经续费但无法续订域名的情况这一页面。


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."
