It is stated that the new version of the IP protocol, IPv6, is the answer to the majority of the problems that were raised during the enormous expansion of the Internet and its transformation to a global communication platform with commercial scope. At the same time it is also stated that IPv6 dominance will not be easy and there will be a period when the two versions of the protocol will co‐exist. In this paper we describe some of the main transition mechanisms that can be deployed in order to facilitate the transition process to the new version of the IP protocol. Furthermore, the presented mechanisms are discussed regarding their usability, usefulness and manageability. Describes the way some of these mechanisms were applied to the Greek Research & Technology Network (GRNET).

This chapter explains how SYRIZA managed to build international support up to the January 2015 election with very limited resources, and against mainstream coverage, by relying essentially on grassroots movements and social media. It also shows how, approaching to power, SYRIZA's political, but also communication strategy, became more institutionalised and relied less on grassroots campaigning. Methodologically, our research is based on the following research techniques: First, interviews with activists and members of the party as well as observations inside its social media team. Second, the study of online content and data from 2006 to 2015. Overall, this chapter shows that SYRIZA's campaign on the Internet relied mainly on alternative media activists who acquired a specific savoir faire and developed international networks during the intense antiausterity social movement that took place in Greece between 2010 and 2013. The campaign was also supported by young experts from the private sector that contributed on a voluntary basis. Nevertheless, its success was mainly due to the European political context and the opportunities it offered to the radical Left, rather than the communication strategy, which in any case suffered from a lack of means and from a somewhat chaotic (non) organisation.
