Domeniile de nivel superior de țară, cunoscute sub denumirea de country code top-level domains (ccTLDs), sunt create și gestionate de IANA (Internet Assigned Numbers Authority), care este responsabilă pentru supravegherea și administrarea lor.
IANA alocă coduri de țară pe baza standardului ISO 3166-1, care asociază fiecărei țări un cod format din două litere.
