IDN Laboratory Test Design Plans
Following the engagement of Autonomica AB, as announced on 19 October 2006, ICANN is pleased to provide more detailed information about the IDN test plans. The IDN testing plans are divided into two phases. The first phase includes laboratory testing that is designed to clarify and document any issues that may arise, if any, when inserting puny-code strings representing top level domains into the root zone. The second phase is an expansion of the laboratory test and will function as a pre-deployment testing primarily for application and user-interface testing.
