首届 ICANN 域名系统 (DNS) 研讨会将于马德里召开

洛杉矶 (LOS ANGELES)——互联网名称与数字地址分配机构 (ICANN) 于今日宣布将在 2017 年 5 月 13 日星期六在西班牙马德里市 (Madrid, Spain) 召开一场新的会议。ICANN DNS 研讨会 (ICANN DNS Symposium) 旨在举行一场技术论坛,使得人们得以讨论有关域名系统 (DNS) 的各类主题。

参会人应当对 DNS 拥有最基本的认识。首届会议的讨论主题将重点关注 ICANN 内部的 DNS 活动,包括:研究、安全、根服务器运营和 IANA 职能等等。如需了解这次研讨会的更多信息,或注册参会,请访问:

ICANN DNS 研讨会将于 OARC 第 26 届会议(即:域名系统——运营、分析和研究中心工作坊会议 (DNS-OARC Workshop))在同一会场先后召开。后者将在 5 月 14 至 15 日召开。这周早些时候在马德里举行的活动还包括:ICANN 全球域名分部 (GDD) 行业峰会 (GDD Industry Summit)(5 月 9 日至 11 日召开),旨在面向新通用顶级域 (gTLD) 项目签约方而举行;以及第 6 届注册运营工作坊 (6th Registration Operations Workshop)(5 月 12 日召开)。


ICANN 的使命在于确保全球互联网的稳定、安全与统一。在互联网上寻找另一个人的信息,您必须在您的电脑中键入一个地址——可以是一个名称或是一串数字。这一地址必须是独一无二的,只有这样电脑之间才能互相识别。ICANN 则负责协调这些分布在全球各地的唯一标识符。ICANN 成立于 1998 年,是一家非营利公益型企业,其社群成员遍布全球各地。ICANN 及其社群致力于确保互联网的安全性、稳定性和互用性。它还负责促进互联网域名系统顶级域之间的竞争,制定相关政策,并促进其他互联网唯一标识符的使用。如需了解更多信息,请参见

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."
