Second Version of Label Generation Rules for the Root Zone (RZ-LGR-2) Released
ICANN is pleased to announce that the second version of Label Generation Rules for the Root Zone (RZ-LGR-2) has been released. RZ-LGR comprises of rules which define a set of criteria for determining valid Internationalized Domain Name (IDN) labels for the DNS Root Zone and their variant labels.
The first version (RZ-LGR-1), released in March 2016, integrated the Arabic script. RZ-LGR-2 integrates five additional scripts, Ethiopic, Georgian, Khmer, Lao and Thai. These label generation rules have been defined by the respective community-based Generation Panels and evaluated by the Integration Panel, following the Procedure to Develop and Maintain the Label Generation Rules for the Root Zone in Respect of IDNA Labels [PDF, 1.4MB].
As additional script proposals for the RZ-LGR are developed and meet the requirements for integration, new versions of the RZ-LGR will be released. Further mechanisms are being investigated for determining how the variant labels may be allocated to those who have applied for top-level domains.
ICANN's mission is to help ensure a stable, secure and unified global Internet. To reach another person on the Internet, you have to type an address into your computer - a name or a number. That address has to be unique so computers know where to find each other. ICANN helps coordinate and support these unique identifiers across the world. ICANN was formed in 1998 as a not-for-profit public-benefit corporation and a community with participants from all over the world. ICANN and its community help keep the Internet secure, stable and interoperable. It also promotes competition and develops policy for the top-level of the Internet's naming system and facilitates the use of other unique Internet identifiers.
