ICANN 注册服务机构认证的有效期为五年。注册服务机构要维持认证状态,必须每五年对注册服务机构认证协议 (RAA) 进行一次续约。

依据 2009 年版 RAA 认证的注册服务机构在续约过程中必须签署 2013 年版 RAA。

ICANN 将在注册服务机构的认证到期日期之前 90 天左右尝试通过电子邮件联系相应注册服务机构,以通知其认证即将过期。此信函将说明该注册服务机构所涉及的未解决合规性问题,并要求注册服务机构确认 ICANN 记录中的注册服务机构联系信息准确无误。


  • 没有逾期未付费用;
  • 符合注册服务机构数据托管要求;
  • 没有其他未解决的合规性问题。

在确定注册服务机构具有良好信誉后,即可对其 RAA 予以续约。

需要特别指出的重要注意事项是,依据 2009 年版 RAA 认证的注册服务机构若有意续约,在收到 ICANN 的提醒后,必须做出肯定回复。如果注册服务机构不予回复,则 RAA 将在期满后过期,同时认证也将失效。

依据 2013 年版 RAA 认证的注册服务机构在收到 ICANN 的续约提醒后应做出回复,但对于有资格续约的注册服务机构,即使未对续约提醒做出回复,其协议也并不会过期。对于通过 2013 年版 RAA 认证的注册服务机构,一般视为有资格续约,但以下情况除外:

  1. 注册服务机构不再符合认证要求;
  2. 注册服务机构未遵守协议规定的义务;
  3. ICANN 已通知注册服务机构其在协议到期日期之前的两年内曾出现三次重大违约行为;或者
  4. 协议在到期日期之前已终止。

如果对 RAA 续约流程有任何问题,请发送至。续约提醒通知将通过 发出。

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."
