The Registration Operations Workshop: Join Us in Buenos Aires

The next Registration Operations Workshop, the fourth of these events, will take place just before IETF-95 on Sunday, April 3, 2016, at the Hilton Hotel in Buenos Aires. The Registration Operations Workshop series is now being co-sponsored by Verisign and ICANN and organized by Viagenie, and we’re looking forward to an engaging set of talks, panel discussions, and conversations with individuals involved with the operation of domain name registrations systems.  

This Registration Operations Workshop will be exploring the recently published proposal for a RDAP Operational Profile for gTLD Registries and Registrars, examining EPP extensions, and discussing experiences as registries and registrars deploy systems used to register domain names. There is still some space on the agenda, so we encourage you to submit a proposal to speak. The deadline to submit proposals is March 8, 2016. Please email an abstract of no more than 750 characters describing your proposal to for the Program Committee to consider. We will accommodate as many proposals as possible during the four-hour workshop. 

While there is no fee to attend the Registration Operations Workshop, we encourage anyone interested to register so that we can appropriately size the room and provide refreshments. Registration opens today, 2 March, 2016 and we look forward to seeing you in Buenos Aires!

    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."
