I would also like to mention
which Slovenian domains were the first under the .si domain.
There wasn't just one, there were several,
because there were some domains already registered under .yu,
I think there were 10, like ijs.yu,
and the University of Ljubljana that used uni-lj.yu.
At the end of 1992 we had these first 10 domains,
which were registered under the top-level domain for Yugoslavia,
transferred under the top-level domain for Slovenia .si.
