The first registered Lithuanian Internet address is still operational. This website www.mii.lt continues to be used by the same research institute, which has been owned by Vilnius University since 2010. After merging the Institute of Mathematics and Informatics on 1 January 2018 with the Faculty of Mathematics and Informatics, the Institute became the Institute of Data Science and Digital Technologies of Vilnius University.
In the comparison of the websites of the world's research centers (research.webometrics.info) performed by Webometrics.com, the website www.mii.lt is still among the leading companies in the Baltic States.
