[Dusan] The question was not about IPv6only client reaching IPv6only client. The question was about IPv4only client in IPv4only network reaching IPv6only client in IPv6only network. Which translation technology provides a solution for that?

[Dusan] Imposing all enterprises to immediately upgrade to dual networks, to be able to talk to IPV6only devices, is not a realist request. The question is what is the translation technology that makes IPv4only client and gateway in IPv4only network, interwork with IPv6only client in IPv6only network?
