Africa didn't get its own web address. Some company registered the Africa Top Level Domain (TLD). This company has total control over the TLD and likely has no relationship to the continent or any of the countries in it. In all likelyhood the registrant for the TLD is a European or American company hoping to make big bucks charging people to use the TLD. In 10 years 99.999999999% of the domains on this TLD will not even involve an African company or individual.
You don't have a clue. A cursory Google search would tell you that it's operated by a South African company (ZACR), which was awarded control by ICANN following a lengthy legal dispute with a Kenyan competitor (DCA).
