We Want to Hear from You on ICANN’s SSR Role and Remit

In mid May, ICANN published a draft statement of its role and remit in the security, stability and resiliency of the Internet’s unique identifiers. After the ICANN meeting in Prague, the public comment period was extended until 31 August 2012. While a number of comments have been submitted, it would be helpful to hear from a broader spectrum of the community on this draft statement.

The statement is intended to be a clear description of ICANN’s technical mission, and a high level view of what ICANN does and does not do in SSR. Although this language is present in many ICANN documents, it can be difficult to find and digest.

The document is a work in progress, and will be updated based on the inputs received in Prague and in the comment forum. Please read it and provide us with your suggestions on ICANN’s role and remit in SSR by commenting in the URL linked at the top of this post. We want to hear from you!


    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."
