Chairman’s Blog: ICANN Congratulates the Internet Society on Turning 25

On behalf of ICANN, we extend our congratulations to the Internet Society (ISOC) on its 25th anniversary.

ISOC is a worldwide advocate for a free and open Internet, for everyone. We respect the work done by ISOC members and chapters, Board of Trustees, and Staff to fulfill the mission of ISOC: By connecting the world, working with others, and advocating for equal access to the Internet, the Internet Society strives to make the world a better place.

Of obvious importance to us is the partnership we have enjoyed as both of our organizations have collaborated and supported each other over the years. In particular, ISOC provided enormous support to ICANN over the long-running and ultimately successful IANA stewardship transition process. For this partnership, we thank you.

The orchestration of your 25th anniversary will be remembered by all who participated. We particularly enjoyed hearing the encouraging stories of the 25 people under 25 years of age from around the world who have already, and certainly will continue to contribute greatly to the Internet. The Internet Hall of Fame inductees were inspiring, too. We were particularly happy to see Jaap Akkerhuis, an active member of the ICANN's Security and Stability Advisory Committee since its inception, and ICANN's liaison to the 3166 Maintenance Agency, honored. Great congratulations to Jaap and all other inductees for this great honor. It was a pleasure and an honor to be there.

We salute you and wish ISOC many more decades of success.


    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."
