Details for ICANN Meeting in Marina del Rey, 12-15 November 2001

The homepage for the 12-15 November 2001 ICANN meeting in Marina de Rey, California, USA, has been posted: <http://www.icann.org/mdr2001>. The meeting homepage includes available information on meeting schedules and agendas, hotel options, visas, webcasting and remote participation, press and media contacts, and sponsorship opportunities.

The meeting will not follow the usual ICANN format. The meeting days November 13-15 will be devoted to a special meeting on the "Security and Stability of the Internet Naming and Address Allocation Systems," to be followed by a meeting of the ICANN Board of Directors on the final afternoon. The first day, November 12, is reserved for normal business meetings not connected with the security focus of the remainder of the meeting.

As always, the ICANN's meeting is open and participation is encouraged. Anyone can attend and there is no registration fee. However, because of the special nature of the agenda for this meeting and because of heightened security concerns, pre-registration will be required to attend this meeting.

The meeting homepage will be regularly updated, so check back often!

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."
