In December 2017, there were more than 41 000 .eu and .ею IDNs, a net decrease of approximately 4 000 since December 2016. The number of IDNs peaked at 67 000 in 2010, and there is a slightly downward trend-line from 2009 to 2017.
Analysis of the .eu and .ею IDN zones (captured in April 2018) reveals that of a total of 40 300 .eu and .ею IDNs, 35 000 are Latin script, 2 000 are Greek script and 3 100 are Cyrillic script (2 000 under ею and 1 100 under .eu). The introduction of .ею has increased the percentage share of Cyrillic script domains in the EU namespace temporarily, due to a cloning of existing Cyrillic script second level IDNs when the .ею launched in 2016. These second level Cyrillic script IDNs will gradually be retired by May 2019, as EURid implements its ‘single script’ policy for the .ею top level TLD.
The majority of IDNs under .eu are in Latin script (holding steady at 88% since 2016). The continuing popularity of Latin script reflects the widespread use of Latin script in many European languages, with accents and diacritics forming the IDN element of the Latin script domains. Some European languages, such as German, Swedish, French, Czech and Polish, use many diacritics. Others (such as English and Dutch) use relatively few. Two EU languages – Bulgarian and Greek – rely on non-Latin scripts (Cyrillic and Greek, respectively).
Aware that mixed-script IDNs pose challenges for users, EURid since 2009 has worked within the ICANN community to introduce the equivalents to .eu in both Greek and Cyrillic script. The aim is to support the objective of enhancing online linguistic diversity by giving EU businesses and individuals the opportunity to register domain names in an entirely Greek script or Cyrillic script environment.
