This chapter summarizes the findings from the previous analyses and discusses the overall legitimacy of the IANA transition process according to the selected normative criteria. The results suggest that despite the IANA transition’s success in removing US government oversight, it neither consisted of nor produced an improved model of multistakeholder governance. Based on the IANA transition case, the chapter concludes that multistakeholderism risks resulting in misleading rhetoric that legitimizes power asymmetries, rather than being a performative concept leading toward the democratization of transnational policy-making. Finally, the chapter calls for a reform of multistakeholder governance toward a model of digital constitutionalism.
