ICANN 政策更新 – 处理恢复的 IPv4 的全球政策提案背景信息


“全球互联网号码资源政策”由 ICANN 与 NRO 之间的 ASO MOU 定义如下,“经所有 RIR 按照其政策制定程序以及 ICANN 同意的互联网号码资源政策,要求 IANA 或任何其它外部 ICANN 相关组织采取具体行动或结果以便实施”。此 MOU 的附件 A 介绍了“全球互联网号码资源政策”的制定流程,包括一项全球政策由每位 RIR 采纳,然后由 ASO 提交至 ICANN 董事会,并由 ICANN 董事会审批。在这里,ICANN 董事会采用自身的程序来审批由 ASO 提交的“互联网号码资源政策”。

除其他特点外,这些“程序”规定董事会将在适当的时候决定,在寻址社群中对提案进行“早期了解”跟踪的 ICANN 员工应该遵循特定全球政策的制定流程。为此,员工应该定期发布背景报告,并提交给董事会以及所有 ICANN 支持组织与咨询委员会,并在 ICANN 网站上公布。

在 2009 年 4 月 23 日的会议中,董事会在寻址社群的讨论中决定,为了地区互联网注册机构的 IPv4 地址块的分配,请求跟踪全球政策提案的制定流程。为响应该请求,提案的状态定期在此网页上进行跟踪,作为 ICANN 机构和更广泛社群的信息来源。跟踪此政策的工作于 10 月 16 日产生了第六个也是最后一个问题。

2010 年 10 月,NRO EC 的主席声明 NRO EC 认为该提案已放弃。值得注意的是,目前在起草阶段的其他提案可能会提交,以实现该放弃提案本欲实现的类似功能。

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."
