	Title           : Problem Statement: DNS Resolution of Aliased Names

This document attempts to describe a set of issues that arises from
the desire to treat a set or group of names as "aliases" of each
other, "bundled," "variants," or "the same," which is problematic in
terms of corresponding behavior for DNS labels.

With the emergence of internationalized domain names, among other
potential use cases, two or more names that users will regard as
having identical meaning will sometimes require corresponding
behavior in the DNS.  It's not clear how to accommodate these
requirements for behavior of such names in DNS resolution; in
particular, it's not clear when they are best accommodated in
registry practices for generating names for lookup in the DNS,
existing DNS protocol elements and behavior, or some set of protocol
elements or behavior not yet defined.  This document attempts to
describe some of these cases and the behavior of some of the possible
solutions discussed to date.

NOTE: Even more than usual, version -02 of this document is a "work
in progress".  Additional updates may be expected between the date of
this document and the DNSEXT meeting in Beijing, and can be found at
