ICANN Posts New gTLD Questions Paper

In September 2004 ICANN published a strategy for the implementation of new top-level domains (TLDs). The strategy called for the implementation of a strategy that would appropriately take into account many relevant technical, economic, socio-political and cultural issues. In light of several new developments regarding DNS operations and structure, ICANN has developed a plan to facilitate implementation of the strategy for the designation of new TLDs.

The staff paper has been drafted to inform about the current status of the implementation of the "New gTLD Strategy". It is also intended to solicit public comments on the completeness of the list of questions therein as well as on the consultation matrix enclosed.

Please also note the following: The paper is a draft and does NOT foreclose any procedures or outcomes of consultations. The draft questions in the question list are open and are NOT to be read as implying particular preferences. Future consultations will welcome contributions from ALL and the draft consultation matrix does NOT imply any exclusivity provisions.

Please submit your comments to <new-gtld-questions@icann.org>. You can view comments at <http://forum.icann.org/lists/new-gtld-questions/>. Deadline for comments is 1 August 2005.

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."
