The Serbian registry now offers the IDN extension .срб (.serbia). Everyone who already owns a .rs name can register this name under the new IDN extension for free until mid June.
You do need to take into account that your domain name will also be written in Cyrillic if you wish to register your name under this extension. It’s already possible to register IDN domain names under certain extensions such as .eu, .com and .lu. IDN names are names which also contain non Latin characters. We now see also more and more IDN extensions with .срб as a new player on this market.
