.si is the Internet country code top-level domain (ccTLD) for Slovenia. It is administered by the ARNES, the Academic and Research Network of Slovenia. In 2010, the registry hosted 80,000 domain names. In 2012, that number increased to 100,000. Domain hacks Domain hacks for the .si TLD are quite popular, since si is second person singular of the verb 'to be' in Slovene. As such, many domains have been created that are using such domain hacks, one of the most popular being zadovoljna.si ('You are pleased', feminine form). Sí also translates from Spanish as yes, so the TLD has been used by some Spanish-language websites. A notable example of this is the Mexican political party MORENA, whose website is found at morena.si. Italian party Sinistra Italiana (abbreviation: SI) also uses Slovenian domain for its website (sinistraitaliana.si). Pepsi uses the URL shortening pep.si. Risk According to research by McAfee performed in 2010, the Slovenian TLD is the tenth most secure.
