  3. Internet Engineering Task Force • IETF is a large open international community of network designers, operators, vendors, and researchers concerned with the evolution of the Internet architecture and the smooth operation of the Internet. • It is open to any interested individual.

  4. IETF IDN Working Group • Mailing List • General Discussion: idn@ops.ietf.org • To subscribe: idn-request@ops.ietf.org • Archive: ftp://ops.ietf.org/pub/lists/idn* • Website http://www.i-d-n.net/ • Chair • James Seng <jseng@pobox.org.sg> • Marc Blanchet <Marc.Blanchet@viagenie.qc.ca>

  5. Primarily Goal • From the charter “The goal of the group is to specify the requirements for internationalized access to domain names and to specify a standards track protocol based on the requirements.” • BoF in Nov 1999, WG formed in Jan 2000 • Spend 6 months gathering requirements • draft-ietf-idn-requirements – Waiting for IESG action • Update charter to include standard protocol specification in Jun 200

  6. WWW Email Mail Format HTTP URI SMTP IDN is here DNS TCP/UDP Internet Protocol (IP) Snapshot of network layers to provide some Internet Service Where is IDN?

  7. Stability and Compatibility • From the charter “A fundamental requirement in this work is to not disturb the current use and operation of the domain name system, and for the DNS to continue to allow any system anywhere to resolve any domain name.” • IDN is changing a fundamental service • IAB RFC2825 –“Issues of I18N, Domain Names, and the other Internet protocols” • A lot of existing Internet Protocols assumed domain names and assumed that it is A-Z, 0-9 and “-” only

  8. Confusions & Consensus • Scripts v.s Language • we deal with script in ISO10646 • Internationalization, Localization and Multilingualism • “I” in IDN is Internationalization • Names v.s Identifier • Domain Names is actually an Identifier • Character Set Encoding • ISO/IEC 10646 also known as Unicode • Matching • Normalization UTR#15 and Case Folding UTR#21

  9. Action Items • An Informational RFC specifying the requirements for providing International character sets in domain names. • A standard track specification on permitting international characters in domain names, including specifying any transition issues. • A standard track specification on an ASCII Compatible Encoding (ACE), to be used in the standard track specification on permitting international characters in domain names. • A standard track specification on normalization of domain name identifiers for the purpose of string comparisons.

  10. Number of Proposals (I-Ds) NB: These are estimated numbers

  11. Outstanding issues • IDN Protocol • DM-IDNS and IDNA • Note: DM-IDNS is superset of IDNA • Matching • Localization in Nameprep • ACE • Reordering • ACE prefix

  12. But only the beginning… • From the charter “The group will not address the question of what, if any, body should administer or control usage of names that use this functionality” • Issues not deal with in IETF • Trademark and Domain Name Dispute Policy • Use of Symbols and drawing characters • Policy on the delegation of IDN • Other business issues? • Deployment?

  13. Conclusion • Many problems • This is not a simple problem • But solutions are emerging • No solution is perfect, engineering compromised • Many confusions • Took us many months to understand the issues but we figure it out • More to come • There are non-technical (e.g. policy & trademark) issues pending which cannot be deal with in IETF
