Here in the Office of the CTO (OCTO), we're busy getting ready for several technically themed events coming up in Madrid, Spain, in May.

12 May Identifier Technology Health Indicators (ITHI) workshop
12 May Registry Operations Workshop (ROW)
13 May ICANN Domain Name System (DNS) Symposium
14–15 May DNS Operations, Analysis, and Research Center (DNS-OARC) workshop

Two ICANN-sponsored events are taking place on 12 May. The day starts with a workshop on OCTO's Identifier Technology Health Indicators (ITHI) project, which is developing metrics to measure the health of the Internet's unique identifier system. After those metrics are defined, ICANN will measure and track them to see the evolution of the "State of Identifier Technologies." This is one of several workshops we are holding to engage with the community to develop those metrics. Registration is free. If you're interested in attending, contact Alain Durand (

The sixth Registry Operations Workshop (ROW) follows the ITHI workshop later that afternoon. The ROW is an informal industry get-together that provides a forum to discuss the technical aspects of registration operations in the DNS. This session will focus on the Registration Data Access Protocol (RDAP). Registration for this event is free as well.

The ICANN DNS Symposium will be held on 13 May. OCTO's SSR team has previously held similar events, but they were focused on the security, stability and resiliency of the Internet's system of unique identifiers that ICANN helps coordinate. This event is the first organized by ICANN with a technical focus on the DNS as the theme. When we began to put the agenda together, we quickly realized we could fill an entire day just describing all the DNS-related projects and activities happening within ICANN. So for this first ICANN DNS Symposium, we've decided to update the community on just that.

Come join us for presentations from a number of different ICANN departments. The agenda [PDF, 451 KB] includes highlights of recent areas of research by the OCTO team, a presentation by the DNS Engineering team on the architecture of the L-Root server, an overview of the Service Level Agreement (SLA) monitoring system by the Global Domains Division, and an update on what's happening at Public Technical Identifiers (PTI) – the group that provides the Internet Assigned Numbers Authority (IANA) functions. We're especially interested in the community's feedback, so we've included time at the end of the day to listen to you. Registration is free! For more information, see the ICANN DNS Symposium webpage.

Finally, ICANN is pleased to be a significant sponsor of OARC 26. The DNS Operations, Analysis, and Research Center (DNS-OARC) workshop runs 14–15 May 2017. The agenda is filled with compelling content related to DNS operations, analysis and research. You can find more information on the OARC 26 webpage, including a link to register.

All events are collocated in the same venue, the NH Madrid Eurobuilding Hotel and occur just after the Global Domains Division Summit, also being held there.

We hope to see you!

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."
