Updated IDN ccTLD Fast Track Process Including Risk Mitigation Measure Evaluation Released

LOS ANGELES – 29 March 2019 – The Internet Corporation for Assigned Names and Numbers (lCANN) today announced the release of the updated Internationalized Domain Names (IDN) country code Top-Level Domain (ccTLD) Fast Track Process Final Implementation Plan (FIP), which includes changes proposed by the Joint ccNSO SSAC Response [PDF, 214 KB] as approved by the ICANN Board on 29 October 2017.

The updated IDN ccTLD FIP [PDF, 988 KB] includes the implementation of the risk mitigation measures evaluation step after the string similarity review process. This evaluation for the relevant requesters of IDN ccTLD strings will be undertaken based on the Guideline for Risk Mitigation Measures Evaluation [PDF, 285 KB]. ICANN will be notifying relevant IDN ccTLD Fast Track requesters regarding their eligibility to ask for an evaluation for the submitted IDN ccTLD string. The requesters will have three months to file the request, along with the mitigation measures, based on the updated IDN ccTLD FIP [PDF, 988 KB].

The updated plan [PDF, 988 KB] supersedes the previous version of the IDN ccTLD FIP [PDF, 850 KB] published on 5 November 2013. Previous versions of the FIP are available at


ICANN's mission is to help ensure a stable, secure, and unified global Internet. To reach another person on the Internet, you need to type an address – a name or a number – into your computer or other device. That address must be unique so computers know where to find each other. ICANN helps coordinate and support these unique identifiers across the world. ICANN was formed in 1998 as a not-for-profit public-benefit corporation with a community of participants from all over the world.

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."
