Title : Registration Restrictions on Internationalized Domain Names - An Overview

IETF has introduced standards-track mechanisms to enable the use of
'internationalized', i.e., non-ASCII, names in the DNS and
applications that use it. This has led, in turn, to concerns that
characters with similar meanings or appearance could cause user
confusion and opportunities for deliberate deception and fraud. Part
of this problem can be addressed by limiting, on a per-zone (or
per-registry) basis, the specific characters that can be used to be a
subset of the list allowed by the standard and by creating
'reservations' of labels that might create confusion with those that
are permitted. The model for doing this for languages that use
characters that originated with Chinese has been extensively
developed in another document. This document discusses some of the
issues in that design and relates them to considerations and
mechanisms that might be appropriate for other languages and scripts,
especially those involving alphabetic characters.
This document is intended to supply a basis for adapting methods
developed for Chinese, Japanese, and Korean to other languages and
scripts. If these adaptations are made carefully and with due
consideratio for local issues, the likelihood of problematic DNS
registrations with be significantly reduced.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
