Revamped Whois Inaccuracy Reporting System Goes Live

A redesigned system for receiving reports of inaccurate domain name registration data has gone live today.

The Whois Data Problem Report System (WDPRS) has a number of advantages over the previous system, which was first introduced in 2002. Among them are:

  • More detailed information is captured from complainants to assist registrars in investigating Whois inaccuracies
  • Duplicate reports regarding the same domain name are not accepted by the system
  • Reports concerning domains already on hold are removed
  • Greater capacity has been introduced to allow for bulk submissions of reports
  • Processes have been put in place to assess registrar compliance with RAA Whois inaccuracy investigation requirements

The revamped WDRPS can be found at


The WDPRS allows the public to file reports of Whois inaccuracy regarding active domain names. The WDPRS transmits Whois inaccuracy reports, via email, to the sponsoring registrars for investigation as required by Section 3.7.8 of the Registrar Accreditation Agreement (RAA)

In 2002, ICANN developed the WDPRS to improve Whois data accuracy and to assist registrars in carrying out their responsibility to take reasonable steps to investigate Whois inaccuracy claims. Although significant system enhancements were made over the past six years to address community needs, a more comprehensive system redesign was determined necessary to realise the system objectives. This new software system also allows ICANN to make future enhancements quickly to respond to community needs.

Since its implementation in 2002, ICANN has seen a significant rise in the number of Whois inaccuracy reports filed through this system. In 2002, approximately 24,000 Whois inaccuracy reports were filed using the WDPRS. In 2008, over 200,000 reports have been filed since 1 March 2008

In an effort to improve Whois accuracy, registrar compliance with RAA investigation requirements, operational effectiveness, data processing, data recovery, and increase data capacity, ICANN commenced WDPRS redesign plans earlier this year. In consultation with the Intellectual Property Constituency, the Registrar Constituency and other community members, ICANN redesigned the system.

Through the redesigned WDPRS, ICANN seeks to address concerns raised by the Internet community regarding system irregularities, the filing of irrelevant claims and insufficient data capacity. ICANN conducted beta testing with external constituencies to ensure operational functionality and usability of the system prior to launching the redesigned WDPRS. ICANN encourages the Internet community to provide comments to ensure the continual improvement of the WDPRS.

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."
