Description of Working Group:

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.

The scope of the group is to investigate the possible means of doing
this  and what methods are feasible given the technical impact they
have on  the use of such names by humans as well as application
programs, as well as the impact on  other users and administrators of
the domain name system.

A fundamental requirement in this work is to not disturb the current
and operation of the domain name system, and for the DNS to continue to
allow any system anywhere to resolve any domain name.

The group will not address the question of what, if any, body should
administer or control usage of names that use this functionality.

The group must identify consequences to the current deployed DNS
infrastructure, the protocols and the applications as well as
scenarios, where applicable.

The WG will actively ensure good communication with interested groups
who are studying the problem of internationalized access to domain

The Action Item(s) for the Working Group are

1. An Informational RFC specifying the requirements for providing
  Internationalized access to domain names. The document should
  provide guidance for development solutions to this problem, taking
  localized (e.g. writing order) and related operational issues into

2. An Informational RFC or RFC's documenting the various proposals and
  Implementations of Internationalization (i18n) of Domain Names. The
  document(s) should also provide a technical evaluation of the
  proposals by the Working Group.

3. A standards track specification on access to internationalized
  names including specifying any transition issues.
