Statement Concerning 11 September 2001 Disasters

To all friends and colleagues across the global ICANN and Internet community:

The disasters of September 11 in the United States were an enormous and tragic event of worldwide proportions.

Many of us learned about it when we had just arrived home or were en route from the ICANN meeting in Montevideo, Uruguay. I have been touched by how so many attendees at that meeting – and others who were not there – have reached out in expressions of shared horror over the events and deep concern for each other's safety and that of our families and friends. It brings home that we are a global community that, whatever our professional differences, care deeply for each other on a human level.

I am pleased to hear from most of you that you have arrived home safely to your respective countries. For those who are still stranded en route, please take care with the rest of your journey. I do hope you can reach home soon. And please do get in touch if there is anything I or the ICANN staff can do to assist.

Of course the entire ICANN community sincerely hopes that none of you or your families or friends has been directly victimized by these horrific events.

All of us, I am sure, extend our deepest sympathies and condolences to all of those and their families and friends - who come from many countries - who have indeed suffered directly and grievously as a result of this evil act.

With warm regards


M. Stuart Lynn
President and CEO

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."
