New gTLD Subsequent Procedures Operational Design Phase

The mailing list is meant as a way for community members to publicly submit questions and feedback to the New gTLD Subsequent Procedures Operational Design Phase (SubPro ODP) program team directly, as it relates to the scope, conduct, output, and timing of the SubPro ODP.

The list is also a depository for all communication between ICANN org and the GNSO Council Liaison to the SubPro ODP.

The mailing list is open for all stakeholders and anyone can subscribe.

Postings to the list will be moderated, and only submissions that concern relevant questions related to the scope and timeline of the ODP will be posted.

The list reflects the open and transparent process of the New gTLD SubPro ODP as all stakeholders are encouraged to share their feedback and responses to submissions are posted publicly.

If you have any questions regarding this process, please contact the project team at

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."
