  • 注册域名之后,该域名在注册有效期内都归您所有,有效期通常为 1 到 10 年。如果您想要继续使用该域名,包括与之相关的所有服务(如网站或电子邮件服务),必须在域名到期之前向注册服务机构续订该域名。如果不续订,您可能会短期或永远失去该域名。ICANN 无权将域名重新转移给您,包括已到期的域名。
  • 确保域名注册有效的过程并不复杂,但是一定要提前了解域名续订的流程以及您的职责,以免遭遇丢失域名这项宝贵资产的风险。为此,您必须始终记得您的注册服务机构关于域名到期的条件与条款,按时缴纳域名相关费用,同时确保向注册服务机构提供最新联系信息,以便您能够收到最新资讯和续订提醒。

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."
