Policies and mechanisms for Internet governance have been topics of heated debate between many different Internet stakeholders, some of whom have very different visions for how and indeed whether the Internet should facilitate free communication of ideas and information. The definition of Internet governance has been contested by differing groups across political and ideological lines. One of the key debates centers around the authority and participation of certain actors, such as national governments and corporate entities, to play a role in the Internet's governance. The position of the US Department of Commerce as the controller of the Internet has attracted criticism from those who felt that its control should reflect its international nature. A hands-off approach by the U.S. Departmetn of Commerce helped contain this criticism. Other areas of controversy included the creation and control of generic top-level domains (.com, .org, and possible new ones, such as .biz or .xxx). There were also suggestions that individual governments should have more control, or that the International Telecommunication Union or the United Nations should have a role in Internet governance.
