When Montenegro became independent from Yugoslavia, its Internet domain name went from .yu to .me.
Top-level domains such as ‘.yu’ and ‘.com’ were assigned to each country by an organization called the Internet Assignment Agency (IANA) until 1998, when the role was transferred to ICANN. Once a country code such as ‘.yu’ is established by IANA, all information about that domain is controlled by the respective country’s government or designated entity.
Even after the Federal Republic of Yugoslavia changed its name to Serbia and Montenegro in 2002, the ‘.yu’ domain continued to be used. When Montenegro declared independence in 2006, ICANN created two new domains: ‘.rs’ for Serbia and ‘.me’ for Montenegro, with the condition that ‘.yu’ be ‘retired’. More time passed, and in 2010, ‘.yu’ was finally abolished.
