The multistakeholder model of Internet governance is based on the belief that the stakeholder groups should be able to agree on the rules and principles in governing the Internet space. The global expansion of the sweeping influence of the Internet has heightened the awareness of international governments on the importance of Internet governance, but since the Internet has developed mostly through voluntary participation by various groups, the organization with the greatest ability to manage the Internet space currently is ICANN(Internet Corporation for Assigned Names and Numbers), the U.S. based organization that manages the assignment of Internet domain names and IP addresses. Although ICANN has attempted to globalize its operation, governments in some nations are voicing dissatisfaction over the fact that the voice of the governments are not adequately represented within ICANN. This paper examines how the concept of multistakeholderissm has been used in WSIS(World Summit on Information Society), ICANN(Internet Corporation for Assigned Names and Numbers) and the ITU(International Telecommunication Union) as an important principle in emphasizing their roles in Internet governance.
