大家都说,ICANN 第 60 届会议是一次成功和卓有成效的会议。你们很多人都知道,这是我们的年度大会 — 这是本年度我们召开的最长会议,除了制定彰显每次 ICANN 会议特点的政策外,主要集中于外展和合作。

由于我们结束了阿布扎比会议,我们将目光转向将于 2018 年 3 月 10-15 日在波多黎各圣胡安市召开的 ICANN 第 61 届会议。这标志着自 2014 年以来我们第一次在北美地区举办 ICANN 会议,我们迫不及待地欢迎大家到北美来。

根据 ICANN 会议战略,圣胡安会议被分类为社群论坛。这是一次为期六天的会议,其中将有多个专门的时间段来讨论社群内外部的工作。这次会议的形式有益于我们所说的"内展"。这的确是一个很好的机会,方便 ICANN 社群聚在一起分享其他目标和愿望,以及探讨他们在努力确保互联网的安全性、稳定性和互用性的过程中遇到的一些挑战。

ICANN 第 61 届会议期间有很多工作要完成,但我们希望你们也能找到时间来探索波多黎各的风景、文化和社会。最近的飓风季节结束后,岛上仍然生机勃勃,肯定会迅速恢复活力的。过去几个月的恢复工作已经证实了扎根于这个岛国文化中的深厚实力和凝聚力。1493 年意大利探险家克里斯多弗·哥伦布 (Christopher Columbus) 发现了波多黎各,现在这里居住者大约 350 万人,我们以拥有生动的文化和较强的社会关系为荣。虽然很多人认为波多黎各只是一个小岛,但它是一个包含 143 个岛屿的群岛。它拥有超过 270 英里的海岸线,其中一些部分的品质在加勒比海地区屈指可数!我们希望你们抽空享受一下这片美丽的土地和我们富有活力的文化。

我们期待在 ICANN 第 61 届会议上看到你们所有人,因为可以肯定那将是另一次具有吸引力、富有成效和有趣的会议。



    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."
