Only the local government is entitled to register a domain name identical to the Hungarian name of a settlement.
If a municipality has an official name in the language of a minority, only the local government is entitled to register the corresponding domain name too. You can find the resolution in priciple of the Advisory Board in this regard here (Hungarian only).
Thus, even the local minority self-government cannot register the minority language name of the given settlement as a domain name. We recommend that in such a case the minority self-government agrees with the local government that the local government registers the name and give it to the minority self-government to use.
