Background on Global Policy Proposal for Handling Recovered IPv4

Global Internet Number Resource Policies are defined by the ASO MOU - between ICANN and the NRO - as "Internet number resource policies that have the agreement of all RIRs according to their policy development processes and ICANN, and require specific actions or outcomes on the part of IANA or any other external ICANN-related body in order to be implemented". Attachment A of this MOU describes the Development Process of Global Internet Number Resource Policies, including the adoption by every RIR of a global policy to be forwarded to the ICANN Board by the ASO, as well as its ratification by the ICANN Board. In this context, the ICANN Board adopted its own Procedures for the Review of Internet Number Resource Policies Forwarded by the ASO for Ratification.

Among other features, these Procedures state that the Board will decide, as and when appropriate, that ICANN staff should follow the development of a particular global policy, undertaking an "early awareness" tracking of proposals in the addressing community. To this end, staff should issue background reports periodically, forwarded to the Board, to all ICANN Supporting Organizations and Advisory Committees and posted at the ICANN Web site.

At its meeting on 23 April 2009, the Board resolved to request tracking of the development of a Global Policy Proposal for the Allocation of IPv4 Blocks to Regional Internet Registries, under discussion in the addressing community. In response to that request the status of the proposal was regularly tracked at this web page as an information resource for ICANN entities and the wider community. A sixth and final issue of the tracking of this policy effort was produced on 16 October.

In October 2010, the Chair of the NRO EC stated that the NRO EC deems the proposal abandoned. It is noted that other proposals, now in the drafting stage, may advance to fulfill a similar function to that intended with the abandoned 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""icann.org"" is not an IDN."
