Domain Name Industry Engagement

Domain Name Industry Engagement

The domain name industry faces increasingly complex challenges with users, new TLDs, and disruptive technologies and trends.

What should ICANN's role be over the next five years for this industry?

Here are just a few examples of the many questions and suggestions that the community is considering in this area:

  • How might ICANN evolve regarding its relationships with the gTLD registrars and registries, ccTLD operators, and IP address registries?
  • How will the removal of gTLD supply constraints and changes in gTLD distribution channels change ICANN's role?
  • Should gTLD registrars and registries be treated as ICANN "customers" or domain name distribution channels?
  • Evolve ICANN's role in supporting the maturation of a healthy unique identifiers ecosystem (domain names, IP addresses and AS numbers).
  • Should ICANN actively encourage business and technical innovation in the DNS? Why or why not? If so, how?

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."
