根区维护人协议 (RZMA)


RZMA 的状态

2016 年 9 月 28 日:ICANN 与 Verisign 签署了 RZMA



在 2015 年 3 月 4 日发送的一封信函中,NTIA 正式请求 Verisign 和 ICANN 联合编制一份提案,其中说明应如何以最佳方式移交 NTIA 的根区管理职责,并在此过程中维护互联网 DNS 的安全、稳定和弹性。2015 年 8 月,ICANN 和 Verisign 应要求向 NTIA 提交了提案

在更新和平行测试 RZMS 的同时,ICANN 与 Verisign 就根区维护人服务协议 (RZMA) 的条款进行了讨论和协商。该 RZMA 旨在确保在管理权移交后维护根区的稳定、安全和可靠运行。ICANN 与 Verisign 就 RZMA 的条款达成共识,继而发布了这些条款以征询公众意见,公共评议期为期 30 天,于 2016 年 6 月 29 日启动。

根据 RZMA 规定,Verisign 将继续提供根区维护服务,对根区的根区签名密钥进行签名管理,以及在收取少许费用的情况下将根区文件和相关文件分配给根区运营商。RZMA 的有效期为八年,旨在让 Verisign 在协议期内继续履行其当前职能,从而提高根区维护运营的安全、稳定与弹性。

此外,RZMA 还赋予了社群一项权能,即在三年后,社群可以通过基于共识、以社群为主导的流程,要求 ICANN 将根区维护职能移交给其他服务提供商。它还允许社群随着根区管理的发展,就服务水平协议和 RZMS 提出修改建议。

按照 ICG 提案的要求,RZMA 于 2016 年 6 月 29 日发布以征询公众意见,该征询期共持续 30 天。2016 年 8 月 9 日,ICANN 董事会通过了一项旨在批准 RZMA 的决议,并指示 ICANN 工作人员推进协议的签署。ICANN 与 Verisign 在 2016 年 9 月 28 日签署了 RZMA。

NTIA 与 Verisign 的合作协议修订完成后,RZMA 将生效。届时,Verisign 将不再履行美国商务部的根区维护人职责。

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."
