为了兑现 ICANN 对多利益相关方模型所做出的承诺,ICANN 组织现诚邀大家针对 IANA 职能交付的运营规划和预算提出宝贵意见。这类文件由两部分构成:《2021 财年公共技术标识符 (Public Technical Identifiers, PTI) 运营规划和预算草案》和《2021 财年互联网号码分配机构 (Internet Assigned Numbers Authority, IANA) 运营规划和预算草案》。《PTI 运营规划和预算》一文概括了执行 IANA 核心职能的相关活动,以及改善系统和流程的相关运营活动。《IANA 运营规划和预算》则不仅介绍了 PTI 的各项活动,还介绍了 ICANN 在充当 IANA 职能运营商这一角色时,除了由 PTI 负责管理的部分以外,ICANN 在执行 IANA 职能的监督和交付工作时所需推进的其他项目和成本等事宜。

ICANN 尝试针对上述文件中提出的计划寻求具有建设性的反馈意见。

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."
