In this paper we provide an overview of the ASCOT project and present intermediate results on investigations concerning address management. ASCOT considers managed vehicular networks, i.e. moving networks attached to public transport vehicles that provide network connectivity to its passengers. We briefly describe how ASCOT positions itself among other projects and activities that focus on moving network aspects. We consider addressing: the pros and cons of the various options for the addressing of end user terminals - including a brief discussion of the relevant end user requirements and the impact on mobility management.
