This book is the Official 2025 Outcome of the Dynamic Coalition on Community Connectivity (DC3) of the United Nations Internet Governance Forum (IGF). DC3 is a multistakeholder group, fostering a collaborative analysis of community networks (CNs), exploring how such initiatives can improve and expand connectivity while empowering Internet users. CNs are connectivity initiatives usually developed in a bottom-up fashion by groups of individuals – i.e., communities – that may contribute to the design, development and management of the network infrastructure as a common resource. Hence, CNs are usually managed according to the governance models established by their community members and may be operated by groups of self-organised individuals or entities such as non-governmental organisations (NGOs), local businesses or public administrations. Further information on DC3 and all previous reports can be found at www.comconnectivity.org.
