为贯彻 ICANN 促进和鼓励域名空间之间良性竞争的责任要求 , 注册服务商之间的域名迁移政策 旨在为域名持有者提供一个直接将其域名从一个 ICANN 委任的注册服务商迁移到另外一个目标注册服务商的程序。该政策还对注册服务商如何处理域名持有者的此类迁移请求提出了标准化的要求。

注册服务商之间的域名迁移政策按照 ICANN 的共识性政策制定流程制定。 GNSO 接受了向其提交的 迁移任务组报告 中包含的 29 条政策建议 , 且这些建议于 2003 年初被 ICANN 理事会采纳。按照理事会的指示, ICANN 工作人员咨询了由各机构群体和 GNSO 社群组成的迁移协助工作组 (TAG) ,以便协调新迁移程序的执行工作。所有 ICANN 委任的注册服务商和非商业性的 gTLD 注册管理执行机构必须遵守该政策。

2008 年 11 月,理事会采纳了对注册服务商之间的迁移政策所做的一些修订。

2004 年 7 月 12 日 , ICANN 宣布 实行注册服务商之间的域名迁移政策 , 该政策由最终政策文档组成 , 相关信息可查看 以 下内容。该政策于 2004 年 11 月 12 日正式生效。初始政策建议要求在政策执行后三个月、六个月和十二个月各进行一次政策审查。该信息区将会根据需要进行更新,包括发布审核流程公众意见征询信息以及任何有关实施细则的所有修订信息。


注册服务商之间的域名迁移政策已被所有 ICANN 委任的注册服务商采纳。将域名迁移给新注册服务商的所有请求必须按照本政策的详细程序(包括下面标准表的内容)处理。 ICANN 委任的注册服务商可按照迁移争议解决政策对注册服务商涉嫌违反本政策争议程序的行为实行争议程序。

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."
