WEBINAR: WHOIS Accuracy Reporting System Phase 2 Cycle 2 Report

On 8 June 2016, ICANN published the WHOIS Accuracy Reporting System (ARS) Phase 2 Cycle 2 report. ICANN will hold an interactive webinar on 16 June 2016, 14:30 UTC to review findings of the study and their implications for the community.

The Cycle 2 report acts as a follow-on to the Phase 2 Cycle 1 report published in December 2015. In Cycle 2, ICANN measured both the overall accuracy for syntax (formatting) and operability (e.g., does an email or telephone call go through?) of a sample of WHOIS records in gTLDs. The results include comparisons based on:

  • Registrar Accreditation Agreements (2009 RAA v. 2013 RAA)
  • Top-level domain types (e.g., new or "legacy" gTLDs)
  • Trends in data from Cycle 1 to Cycle 2
  • Regional accuracy differences, including two new sub-analyses: reasons for error by region and language script type vs. accuracy

The WHOIS Accuracy Reporting System is an ICANN initiative born out of recommendations from the 2012 WHOIS Review Team to improve oversight of the WHOIS Program. ICANN committed to proactively identifying potentially inaccurate gTLD WHOIS contact data and forwarding potentially inaccurate records to gTLD registrars for investigation and follow up. The ARS reports provide information on nonconformances (based on the applicable Registrar Accreditation Agreement), which ICANN's Compliance team uses for follow-up with registrars regarding potentially inaccurate records.

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."
