Tec Monterrey and the Fourth LAC DNS Forum

Lac dns forum 12dec17 en

Some say the key to sustainable development is the knowledge economy. A place that exemplifies this idea in the Latin American and Caribbean (LAC) region is Monterrey, Mexico. The city is home to the Monterrey Institute of Technology and Higher Education – also known as Tec. This educational leader promotes knowledge, from creation to application, for the whole scientific spectrum. One area is Internet services, and it is not by chance that is proudly located in Monterrey.

On 16 November, we had the privilege to visit Monterrey to run the Fourth LAC Domain Name System (DNS) Forum, hosted by ICANN supported the forum, along with the Latin American and Caribbean ccTLDs Organization (LACTLD), the Latin American and Caribbean Address Registry (LACNIC), the Internet Society (ISOC), and the Public Interest Registry (PIR). We engaged with the local community by including the forum in the Monterrey's Entrepreneurship Festival, a yearly gathering for technology professionals, startups, investors, and researchers.

Our partners organized the agenda around four pillars:

  • DNS ecosystem and market trends
  • Domain name usage best practices
  • DNS security
  • Entrepreneurship in the Internet

This approach was a success, with attendees lining up before each session to get seats, and asking well-informed questions in the discussions.

You can review the program on the LAC DNS Forum's permanent website (yes, great news!), prepared as a courtesy by Also, take some time to watch our video recordings and download presentations from the YouTube channel.

Many thanks to our Board Members; ICANN’s Global Domains Division (GDD) and Security, Stability, and Resiliency (SSR) team; community members; and business leaders for helping to deliver a memorable LAC DNS Forum. We’d like to extend a special thank you to Monterrey Tec for the warm welcome and for the opportunity to share ideas for an innovative and secure DNS environment. We learned a lot with all of you and look for your participation in the 2018 LAC DNS Forum.


    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."
