Forthnet, an operator in Greece, started deploying IPv6 in their network in 2013. They chose to use the transition technology, Dual Stack Lite(DS-Lite), to help their transition from IPv4. DS-Lite tunnels IPv4 traffic over IPv6 between the customer and a Carrier Grade NAT(CGN) box, which then uses an IPv4 address from an address pool. While similar to generic CGN, DS-Lite allows the operator to run IPv6 in their core.
In this presentation from Anastasios Chatzithomaoglou at the RIPE 67 conference, he provides some statistics about IPv6 usage on their network, explains some of the issues they had with customer premise equipment (CPE) and goes into great detail on their DS-Lite implementation. He also explains at some length how the Port Control Protocol (PCP) can work with DS-Lite to aid in the transition to IPv6.
Check out the slides from his talk at RIPE 67, which are now available for download. You can also view the video of his presentation:
