Email from Tina Dam to Registry Operators and Sponsors

Subject: Temporary increase in access to the shared registration system

Dear Registries and Sponsors,

ICANN received an inquiry about the need for a temporary increase in access to the shared registration system for registration of new domain names. This increase is due to a specific marketing program that is anticipated to result in a temporary significant increase in new domain name registrations.

ICANN has been asked if this raises an issue under the equivalent access provisions of the Registry Agreement. In this instance the increase in access is not a violation of the equivalent access provision: all registrars will still be able to register new domain names as their demand requires and the pursuit of this opportunity by one registrar does not preclude others form pursuing similar endeavors. Marketing programs such as these enhance and promote competition in a way consistent with ICANN's mission.

This email will be posted online at Please let me know if you have any questions to the above.

Best regards,

Tina Dam
Chief gTLD Registry Liaison

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."
