ICANN CEO Congratulates Newly Elected ITU Secretary-General Houlin Zhao

Fadi Chehadé, The President and Chief Executive Officer of the Internet Corporation for Assigned Names and Numbers (ICANN) has extended his congratulations and best wishes to the newly elected Secretary-General of the International Telecommunications Union (ITU).

"We extend our heartfelt congratulations to Houlin Zhao on his election as the ITU Secretary-General," said Chehadé. "His global support was punctuated by the fact that he obtained 152 votes of the 156 countries that were present and voting in the election."

Zhao will succeed current ITU Secretary-General Dr. Hamadoun Toure in January and Chehadé made a point of underscoring Dr. Toure's contributions to enhancing lines of communication with ICANN.

"We are grateful to Dr. Toure for the bridges he helped build between the ITU and ICANN," said Chehadé. "Our interactions have been built on a foundation of mutual respect and a shared belief that the Internet has an increasingly important role in global socioeconomic development. We are enthused at the prospect of continuing those efforts with Houlin Zhao."

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."
