The Inter-Registrar Transfer Policy (IRTP) is a consensus policy adopted in 2004 to provide a straightforward procedure for domain name holders to transfer domain names between registrars. Initial assessments identified a wide range of issues related to transferring domain names, which resulted in the issues being categorized into subsets. In October 2012, the Generic Names Supporting Organization (GNSO) Council requested an Issue Report on a remaining set of IRTP issues, which are collectively referred to as the Inter-Registrar Transfer Policy (IRTP) Part D.

The issue report addressed the following topics:

  1. Whether reporting requirements for registries and dispute providers should be developed, in order to make precedent and trend information available to the community and allow reference to past cases in dispute submissions;
  2. Whether additional provisions should be included in the TDRP (Transfer Dispute Resolution Policy) on how to handle disputes when multiple transfers have occurred;
  3. Whether dispute options for registrants should be developed and implemented as part of the policy (registrants currently depend on registrars to initiate a dispute on their behalf);
  4. Whether requirements or best practices should be put into place for registrars to make information on transfer dispute resolution options available to registrant;
  5. Whether existing penalties for policy violations are sufficient or if additional provisions/penalties for specific violations should be added into the policy;
  6. Whether the universal adoption and implementation of EPP AuthInfo codes has eliminated the need of FOAs.


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."
