ICANN Marks 10 Years Since the IANA Stewardship Transition

Ten years ago today, a historic milestone was reached in the evolution of Internet governance. On 1 October 2016, the U.S. Department of Commerce's National Telecommunications and Information Administration transitioned its stewardship of the Internet Assigned Numbers Authority (IANA) functions to the global multistakeholder community.

The transition completed a process that had been envisioned when the Internet Corporation for Assigned Names and Numbers (ICANN) was established in 1998. It also marked something larger: The global Internet community had come together to develop a way to oversee critical Internet functions through a multistakeholder model.

For billions of Internet users, 1 October 2016 was an ordinary day online. Websites loaded, emails arrived, and the Domain Name System (DNS) continued to work as expected. Behind that continuity were years of work by hundreds of volunteers and participants from the ICANN community, ICANN organization, and the broader Internet community. Governments, businesses, civil society, technical experts, academics, and individual users worked across borders and stakeholder groups to develop the transition proposal and accompanying accountability reforms.

The transition was a significant test of that multistakeholder approach. Ten years later, the Internet continues to benefit from ICANN's multistakeholder model. As the Internet has become more essential for our daily lives, the IANA functions - encompassing the DNS, Internet Protocol address resources, and protocol parameters used by the Internet Engineering Task Force - continue to operate in a secure and stable manner. The ICANN community continues to successfully address complex technical and policy changes.

From Transition to a Decade of Collaboration

The transition strengthened the community's role in ICANN's accountability. The Empowered Community, established in the ICANN Bylaws as part of the accountability reforms accompanying the transition, gives the community specific powers to hold the ICANN Board and organization accountable. These include powers related to budgets, Bylaws changes, and Board directors. It put into practice a central principle of the transition: greater community responsibility accompanied by stronger mechanisms for accountability.

The transition also led to broader enhancements to ICANN's accountability. Based on community recommendations adopted by the Board, strengthened accountability mechanisms were implemented. As a result, the newly developed Empowered Community gave a clear voice to the ICANN community across ICANN's planning work and any amendments to ICANN's governing documents.

This model of cooperation has helped the community navigate major technical changes. In 2018, ICANN successfully completed the first rollover of the DNS Security Extensions root zone key signing key. Years of preparation and coordination among ICANN and the global technical community made it possible to change a critical element of the DNS while maintaining its secure and stable operation.

The work to make the Internet more multilingual provides another example. Advancing Internationalized Domain Names and Universal Acceptance requires expertise that no single organization or stakeholder group possesses. Language communities, technical experts, governments, businesses, and other participants have worked together to address both linguistic and technical challenges. More than 270 script community volunteers from 44 countries contributed over nine years of work that enabled 26 scripts in the DNS.

That community-driven approach also continues to shape the evolution of the DNS. In 2026, the New Generic Top-Level Domains Program entered its next application round following years of community policy and implementation work. Competition, consumer trust, and consumer choice remain important considerations as the program moves forward.

A Model Reaffirmed

The 10th anniversary comes at an important moment for Internet governance. In December 2025, the World Summit on the Information Society 20-year review reaffirmed the multistakeholder approach to Internet governance, recognized the role of the technical community, and commended progress toward a multilingual Internet.

The IANA stewardship transition remains one of the most significant examples of that model in practice. Its success depended on people with different interests, expertise, and perspectives reaching agreement on how to move forward. The decade of progress since has required the same kind of collaboration.

As ICANN marks this anniversary, we recognize all those whose work made the transition possible and those who continue to contribute to the Internet's coordination today. Their collaboration demonstrates the enduring value of multistakeholder decision-making in supporting a stable, secure, and globally interoperable Internet.
