IDN Variants
Background:
Internationalized Domain Names (IDNs) are domain names in different (non-ASCII) scripts – e.g. Arabic, Chinese, Cyrillic, Devanagari, Greek …
An IDN Variant TLD is an IDN TLD that looks like or is considered interchangeable with another by a user of the related writing system – e.g. in Simplified & Traditional Chinese

Arabic
Possible Examples of IDN Variants
IDN variant can look alike or be considered interchangeable in other ways – definition based on script
5Updated as of 1 July 2014
Problem: How to decide which characters to allow to form IDN TLD
labels? How do we decide if two such labels are variants of each
other?
What is the issue we are trying to resolve? What have we done to date?

What are Label Generation Rules? Rules which define how to form a valid label for a domain
name
Each script has its own Label Generation Rules (LGR) The LGR defines:
Which code points are permissibleWhich code points have variantsAre there any label level additional checks Which labels formed by these code points may be
allocated
Label Generation Rules (I)
7Updated as of 1 July 2014
Basic LGR Principles for the root zone:
Different languages may use the same script slightly differently
As root zone is a globally shared resource, the LGR must provide a consistent treatment for each script across all languages using the script
LGR to be developed by script communities proposing solutions and ICANN integrating them into the root zone LGR – balance linguistic expression vs. security and stability concerns
Label Generation Rules for the Root Zone (II)
8Updated as of 1 July 2014
Script-specific LGR proposals need to be developed by the community; and then integrated by the Integration Panel.
ICANN is seeking volunteers to form new (or join existing) LGR Panels for all scripts currently in use
Without a community-based Generation Panel for a given script, there is no process for handling IDN labels in the root for that script. No IDN Variant TLDs for a script will be implemented until this is completed.
What needs to be done? Generation Panels from the community
