IDN Laboratory Testing Progress

19 October 2006

ICANN continues to make progress toward laboratory testing for strings corresponding to internationalized top level labels (IDNs). The purpose of the laboratory tests were described during the ICANN meeting in Morocco held earlier this year ICANN and they are being designed and conducted under the guidance of the ICANN Presidents Advisory Committee for IDNs.

ICANN is very pleased to be able to announce the engagement of Autonomica AB to develop, conduct and report the results of the laboratory test. The test will include insertion of a Punycode string into the "root" as replicated in a laboratory environment. The purpose of these tests is to clarify and document any issues that may arise, if any, when inserting puny-code strings representing top level domains into the root zone.

Among ICANN's core values is the technical security and stability of the DNS. Therefore, laboratory technical tests of the viability of internationalized top level levels and the effect they may have on the DNS is being done before insertion of such labels in the root servers. After the performance of the laboratory test and after appropriate consultation with interested entities, a live root test will be initiated. The live root test process and making participation publicly available is being discussed by the President's Advisory Committee for IDNs. The committee will publish a recommendation in this regard as soon as it is finalized. It is important to note that participation in these tests are not mandatory nor will participation create a favouable position when IDN TLDs are designated.

As soon as the test design and framework has been developed by Autonomica, it will be made available online at http://www.icann.org/topics/idn/. ICANN welcomes replications of the test and will post any results online for public review and for comparison opportunities.

The agreement between ICANN and Autonomica plans to complete the laboratory test and report the results by the ICANN meeting in Sao Paolo. After that reporting a determination will be made in a collaborative manner as to whether it is considered technically appropriate to initiate a test of punycode string directly in the root zone.

The criteria and list of the strings that will be used for the testing purposes is being worked on by a sub-group of the Presidents Advisory Committee for IDNs and the paper describing this initiative will be published shortly.
