IANA Stewardship Transition Coordination Group – Announcement Regarding Community Comments

The IANA Stewardship Transition Coordination Group (ICG)'s Request for Proposals [PDF, 84 KB] from the operational communities noted the following: "While the ICG is requesting complete formal proposals through processes convened by each of the operational communities, and that all interested parties get involved as early as possible in the relevant community processes, some parties may choose to provide comments directly to the ICG about specific aspects of particular proposals, about the community processes, or about the ICG's own processes. Comments may be directly submitted to the ICG any time via email to icg-forum@icann.org."

The ICG will next be discussing the protocol parameters and numbers proposals on February 6. As such, the ICG requests that community comments concerning those two proposals or the processes used to create them be received by February 4 at 23:59 UTC. Comments received after that time will not be considered as part of Step I of the ICG's Proposal Assembly and Finalization Process [PDF, 89 KB] for the protocol parameters and numbering proposals.

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."
