Inter-Registrar Transfer Policy Denials Definitions PDP

Open: 15 September 08
Closed: 6 October 08

Explanation: The GNSO Council approved on 4 September 2008 a motion on the Inter-Registrar Transfer Policy (IRTP) Denial Definitions Public Development Process (PDP). The motion, which is pending for Board action, proposes new texts [PDF, 49K] for two of the nine denial reasons (#8 and #9) while recommending that work on denial reasons #5 and #7 be suspended until such time as a Policy Development Process is initiated on PDP C on IRTP operational rule enhancement as outlined in the Inter-Registrar Transfer Policy Issues PDP Recommendations of 19 March 2008.

The public is invited to submit comments until 6 October 2008 before final consideration by the Board.

Staff member responsible: Marika Konings

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""icann.org"" is not an IDN."
