DNS 风险评估(第一次复议)公众意见征询

在 2013 年 11 月召开的 ICANN 第 48 届布宜诺斯艾利斯会议期间,ICANN 理事会采纳了 ICANN DNS 风险管理框架(下称"框架");2014 年 2 月,一组选定的 ICANN 工作人员使用该框架进行了初步(有限范围)的 DNS 风险评估。

此次初步 DNS 风险评估旨在根据互联网的变革本质和 ICANN 的多利益主体模式作为一次试运行。

有关此次评估的结果,请访问此处 [PDF, 432 KB],其格式为的机构群体的征询文件。此外,反映最初确定的风险的相应风险分类可在此链接 [PDF, 312 KB] 中的"灵活性模型"(resilience model) 内找到。

在 ICANN 第 50 届伦敦会议期间,ICANN 将与机构群体召开一次会议,讨论上述征询文件、在该文件中提出的问题以及最初确定的风险。

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."
