Successful Evaluations of .test IDN TLDs

31 January 2008

In October 2006, ICANN engaged Autonomica AB of Stockholm, Sweden, to  
develop, conduct, and report on the results of laboratory testing of  
internationalized top-level domains in a setting corresponding to the  
public root. On 7 March 2007 the result of the laboratory tests were  
reported successfully. The laboratory technical test was one of the  
prerequisites to eventual insert internationalized top level labels in  
the root zone, which subsequently were done and the associated test  
facility was launched.

Following the project plan, Autonomica then conducted a replication of  
the laboratory test, live in the DNS. Quoting from their report:

"Autonomica AB has, under a contract with ICANN, investigated whether  
the addition of top level domains containing encoded internationalized  
characters (so called IDNs) to the public root zone for testing  
purposes has any impact on the iterative mode resolvers used to look  
up the information. No impact at all could be detected. All involved  
systems behaved exactly as expected."

Therefore, the Automomica test raised no issue regarding the ability  
of root-severs and iterative mode resolvers to handle IDN TLD queries.

Details of the test result can be found here [PDF, 129K].

For any questions or request for additional details of the test design  
and result please contact Tina Dam at tina.dam at icann.org.
