Policy Implementation Update

ICANN announces the implementation of amended rules for the Uniform Domain Name Dispute Resolution Policy (UDRP).


The UDRP is a consensus policy that is applicable to all ICANN-accredited registrars. The updates include:

  1. "Lock" and "pendency" are now defined terms in the UDRP Rules;
  2. UDRP complainants no longer have to transmit a copy of the complaint to the respondent (rule 3(b)(xii));
  3. Rule 4(b) requires registrars to lock the disputed domain name(s) within two (2) business days of receiving a UDRP complaint from a UDRP provider;
  4. Rule 4(e) provides that when a UDRP provider informs the registrar that the UDRP proceeding has been withdrawn or dismissed, the registrar must remove the lock within one (1) business day of receiving notice;
  5. Rule 5(b) provides that respondents may request an additional four (4) calendar days to respond to a complaint and UDRP providers will automatically grant the extension, if requested;
  6. Rule 16(a) provides that registrars must notify the parties, the provider and ICANN of the date for implementation of the decision within three (3) business days of receiving the decision from the provider;
  7. Rule 17 outlines a new procedure to be used in cases that are settled between parties outside the UDRP case.

These amendments to the UDRP rules were designed to reduce the risk of cyberflight during a UDRP proceeding.

On 23 September 2013, the ICANN Board adopted the GNSO Council Policy Recommendations on the Locking of a Domain Name subject to UDRP Proceedings as set forth in the Final Report (see [PDF, 1.01 MB]).

The Generic Names Supporting Organization (GNSO) unanimously approved at its meeting on 1 August 2013 the recommendations of the Locking of a Domain Name subject to UDRP Proceedings PDP Working Group. The 17 recommendations are intended to clarify and standardize the process for locking of a domain name subject to UDRP Proceedings, including:

  • Definition of "locking"
  • Requiring registrar to apply lock within 2 business days following request for verification
  • Removing obligation for complainant to notify the respondent at the time of filing, but add automatic extension of 4 days to response time upon request
  • Step by step clarification of requirements of different parties involved
  • Development of educational and informational materials to assist in informing affected parties of new requirements and recommended best practices

Following ICANN Board approval, an Implementation Review Team ("IRT"), comprised of GNSO Working Group members, was convened and worked with ICANN staff in drafting the amended UDRP Rules. ICANN staff held regular meetings with the IRT to ensure that the recommendations were implemented in accordance with the Working Group's intent.

Effective Date

These new requirements will take effect and will be enforced by ICANN as of 31 July 2015. All ICANN-accredited registrars are required to comply by this date.

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."
