Below you will find links to the discussions taking place in the operational communities as they develop their responses to the ICG Request for Transition Proposals.

Domain Names

Cross Community Working Group The Domain Names community developed a Cross Community Working Group (CWG) to Develop an IANA Stewardship Transition Proposal on Naming Related Functions.

Membership in the CWG is open to members appointed by the chartering organizations. In addition, the CWG will be open to any interested person as an observer.

Numbering Resources

NRO/RIRs NRO (Number Resource Organization)
Including Regional Internet address Registries: AFRINIC, APNIC, ARIN, LACNIC, RIPE-NCC

The 5 Regional Internet address Registries (RIRs) each undertook community consultations in their respective regions from September to November 2014. Details and results of these consultations will be reported via the RIR websites.

From these consultations, the NRO developed a Consolidated RIR IANA Stewardship Proposal Team (CRISP Team) which developed the numbering resources community final proposal.

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."
