Nowadays, the Internet Protocol is facing the version change; IPv4 (the old version of IP) will be replaced by IPv6 (the new version of IP) in the long run. Although they are based on the very same concept, the two protocols are not compatible with each other. This chapter deals with the coexistence issues, which might arise due to the simultaneous existence of IPv4 and IPv6. On the other hand, this chapter also covers transition concepts: how IPv6 only hosts can communicate either over IPv4 only networks, or with IPv4 only hosts in the Internet of the future.
