Total number of IDNs since 2009. There were approximately 7.5 m IDNs as at December 2017. A drop in registrations of 15% (approximately 1.2 registrations) during 2017 is mainly due to a change in policy by the Viet Nam registry (.vn) which saw registrations at the second level under .vn fall from 977 000 in 2016 to 5 000 in 2017, coupled with a slight decline in registrations across the board.
Looking at the change in top and second level IDN registrations between 2015 and 2017, the data indicates a growth rate of 9%.
