Governance involves establishing institutions to resolve conflicts and facilitate cooperation. International regimes are systems of rules and norms that constrain nation-state behavior. There are several theories about why international regimes emerge, including hegemonic stability theory, epistemic communities, and constructivism. International regimes have addressed issues related to the domain name system, e-commerce, intellectual property rights, and the digital divide. The Domain Name System originated from a system administered by Jon Postel and was later established under ICANN with criticism over its relationship with the US Department of Commerce.
