ICANN 和威瑞信宣布启动为期 90 天的根区管理系统“平行测试期”

按照此前计划,ICANN 和威瑞信 (Verisign) 公司已于 2016 年 4 月 6 日启动为期 90 天的"平行测试期",以验证 IANA 管理权移交成功完成后,通过根区管理系统 (RZMS) 所生成的根区文件数据是否保持完整。这是为了确保互联网根区持续稳定和安全的重要一步。"平行测试期"是 ICANN 和威瑞信于 2015 年 8 月向美国国家电信和信息管理局 (NTIA) 提交的提案中的一部分。该提案根据 NTIA 的要求,确定了怎样才能最好地将 NTIA 涉及根区管理方面的管理职责移交给全球多利益相关方社群,从而能够维持互联网域名系统 (DNS) 的安全、稳定和弹性。

本"平行测试期"将用于确认现有的 RZMS 及其平行测试版(即去除了 NTIA 授权的版本)所生成并发布的每个根区文件均完全相同。从平行测试期起直至 IANA 管理权成功移交之时,RZMS 仍将继续生成经由 NTIA 授权的权威根区文件。

平行测试期计划将持续 90 天。当 RZMS 及其平行测试版所生成的文件中不存在任何无法解释的差别时,测试期即可宣告成功。但如果在此期间发生了无法解释的差别,则应当及时处理问题,并重新启动 90 天的平行测试期。

威瑞信公司将在整个测试期内逐日发布对比报告,具体请参见公司网页。ICANN 则将在其管理权移交实施页面上发布月报。

RZMS "平行测试期"是 ICANN 应预期发生的 IANA 管理权移交的要求,所做的大量实施规划工作中的一环。2014 年 3 月 14 日,NTIA 宣布有意将针对 IANA 职能的管理权移交给多利益相关方社群。即在 IANA 管理权成功移交之时(预定为 2016 年 9 月),NTIA 目前所担任的根区管理人 (RZA) 的职责也将不复存在。

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."
