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.

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

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 UTR15 and Case Folding UTR21
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.

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
