Requirements for Implementing Rights Protection Mechanisms in Name Collision Mitigation Framework Now Available

[Update: the previous version of the Assessment Addendum published on 7 November 2014 has been revised and updated based on a number of questions received. View the Updated addendum [PDF, 416 KB]. View the Redline [PDF, 77 KB] version showing changes from the previous Assessment Addendum]

Following a 90-day public consultation period, ICANN is implementing a solution to allow new gTLD registries to release names from their Second-level Domain (SLD) Block Lists while complying with all Rights Protection Mechanism requirements. ICANN will provide affected registries with an addendum [PDF, 416 KB] to their Name Collision Occurrence Assessments that explains how to release blocked names, by 14 November 2014.

To release these names, the approach requires registry operators to implement an "exclusive registration period" that meets the criteria described in its "Assessment Addendum," limited to the following category of names:

  • Included on the Second-level Domain Block List provided in the registry operator's Alternate Path to Delegation Report.
  • Recorded in the Trademark Clearinghouse.
  • Withheld from allocation by a registry operator during its Sunrise Period or Claims Period.

Registry operators can choose one of two paths for conducting an exclusive registration period:

  1. Option A – ICANN Selected Exclusive Registration Dates

    Registry Operator may opt into one of two exclusive registration periods published by ICANN by providing a minimum of ten (10) days notice to ICANN of its decision to do so, followed by at least thirty (30) days of an exclusive registration period. The start dates for each exclusive registration period will be publicized to enhance awareness among eligible rights holders. ICANN strongly encourages this option to streamline communications and expedite the process for release of names from the SLD Block List.

    For Option A, Exclusive Registration Period timeframes are as follows:

    • Exclusive Registration Period 1: 10 December 2014 – 9 January 2015. Registries may opt in by 30 November 2014.
    • Exclusive Registration Period 2: 16 January 2015 – 15 February 2015. Registries may opt in by 6 January 2015.
  2. Option B – Registry Operator Selected Exclusive Registration Dates

    Registries not opting for Option A may provide an exclusive registration period under the same requirements as the registry's original Sunrise Period:

    1. Providing a minimum of thirty (30) days notice of the exclusive registration period followed by a start-date (at least 30 days) exclusive registration; or
    2. Providing an end-date (60 days) exclusive registration period, provided that first-come-first-served is not used as the allocation mechanism.

All registry operators must submit their exclusive registration period information to ICANN via the GDD Portal.

The 90-day consultation was specified in measure II, Section C of the Name Collision Occurrence Assessment and a resolution of the New gTLD Program Committee of the ICANN Board.

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."
