Expert Working Group (EWG) & Reinventing WHOIS – Read, Discuss, Get Involved!

The Expert Working Group on gTLD Directory Services (EWG) has been gratified by the ICANN community's robust discussion of its Final Report [PDF, 5.11 MB], which proposes an unprecedented "paradigm shift" to replace today's WHOIS system with a next generation Registration Directory Service (RDS).

The EWG welcomes every person's thoughtful analysis and feedback, and we hope everyone takes time to read the Final Report. As can be expected with such a complex topic, misconceptions have emerged about the EWG's recommendations. To address this, additional material has been posted on the EWG webpage, including a statement by EWG member Stephanie Perrin, an additional EWG statement, FAQs, and summary slides.

We hope interested community members will join us online and in person tomorrow morning (Wednesday, 25 June at 8:00 am) in London [link] to continue discussions and advance our collective journey to reinvent today's WHOIS system.


    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."
