RAA の下で、ICANN は、RAA のセクション 5.3 で規定される状況および条件に従って、有効期限の前に RAA を終了することができます。また、レジストラは、書面による 30 日前の通知を ICANN に提出することにより、自発的に RAA を終了することができます。この通知は、レジストラの正式なレターヘッドを使用し、レジストラ企業の権限を有する役員が署名した上で、宅配便、郵便またはファックスによって配達されなくてはなりません。

RAA の終了により(ICANN またはレジストラのいずれによる終了かを問わず)、終了されたレジストラがスポンサーとなっていたドメイン名は、ICANN 認定レジストラに移転されなくてはなりません。ICANN では、認定解除されたレジストラからの移転手順 [PDF, 128 KB] に従って、ドメイン名の適切な移転およびレジストラントの保護を確保します。

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."
