ICANN is pleased to announce that Tina Dam and Karen Lentz have joined ICANN as Chief gTLD Registry Liaison and gTLD Registry Liaison.

In response to community feedback, ICANN has placed a high priority on both ensuring responsive services to registries and ensuring compliance with all agreements entered into by ICANN.

Tina Dam (Chief gTLD Registry Liaison, dam@icann.org) is a long-time member of the ICANN community. She formerly held the position of "Registry Relations Manager" with ICANN-Accredited Registrar Ascio Technologies (FKA Speednames).

Karen Lentz (gTLD Registry Liaison, lentz@icann.org) is new to ICANN and domain names, but has a strong background in compliance issues having previously worked in Rights & Permissions for Science Magazine.

Tina and Karen are available immediately to assist gTLD registries with any ICANN-related issues. They will also be responsible for issues concerning compliance with the requirements of agreements between ICANN and registry sponsors and operators.

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."
