Registration of names in the DNS has traditionally involved restrictions
beyond those very few required by the DNS itself, both to match
requirements imposed by applications (the 'hostname' rules) and avoid
confusion among similar-looking names. With the introduction of
internationalized domain names (IDNs), the standards make a much larger
number of characters available for inclusion in domain names as they appear
to the user. Concerns similar to those caused the original adoption of the
hostname rules have led several groups to explore models for appropriate
restrictions by registries on the IDNs that can be registered and whether
some combinations of names should be restricted even if the characters in
them are valid. This document explores those issues, including how methods
developed for Chinese, Japanese, and Korean can be adapted to other
languages and scripts, and makes suggestions for mechanisms registries
might use to define and implement such rules.
