According to the recently released World Report on Internationalised Domain Names (IDNs) by EURid and UNESCO, IDNs now comprise 3% of the world's domains, with a total number of 8.7 million IDNs registered as of December 2016 (with a growth rate of 28% compared to the previous year). The number includes IDNs registered both in generic top-level domains and country code top-level domains, both at first and second levels. Most IDNs are registered in the Asia and Pacific region. The report concludes that IDNs help to enhance linguistic diversity in cyberspace, and that IDN scripts are an accurate predictor of the language of web content. But it also notes that there is a slow progress in addressing some of the major challenges to the mass uptake of IDNs, such as their poor usability in email, online user identifiers, and in browsers, applications, and devices.
