.mobi Registry Agreement

On 30 March 2017, ICANN (Internet Corporation for Assigned Names and Numbers) and Afilias Technologies Limited, entered into a renewal Registry Agreement under which Afilias Technologies Limited operates the .mobi top-level domain. The renewal agreement may be viewed by following the links below.

In connection with the renewal of the .mobi Registry Agreement, ICANN and Afilias Technologies Limited have agreed to implement the incorporation of unique legacy-related terms of .mobi through an "Addendum" to the Registry Agreement. The Addendum will amend the terms of the .mobi Registry Agreement. Where the Addendum provides for a different formulation of a provision, the provision in the Addendum will control. Similarly, where the Addendum states that a provision will have "no force or effect", the referenced provision in the Registry Agreement will be considered not applicable. The terms of the Addendum will not be affected by future global amendments under Sections 7.6 or 7.7 of the existing New gTLD Registry Agreement, which will enable future global amendments to proceed while preserving the unique terms applicable to .mobi. If an amendment is approved under Sections 7.6 or 7.7 that would amend or modify any terms of the .mobi Registry Agreement that are modified by the Addendum, ICANN and Afilias Technologies Limited have agreed in the Addendum to (i) enter into good faith discussions regarding whether an amendment to the Addendum is appropriate in light of the global amendment and (ii) mutually agree on an appropriate amendment to the Addendum or the .mobi Registry Agreement.

Effective 01 September 2020, the Registry Agreement was assigned by Afilias Technologies Limited to Afilias Limited, which now operates the .mobi top-level domain.

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."
