IPv6 has always been a hot topic! Available for years, many ISP's deployed IPv6 up to their residential customers. In Belgium, we were for a long time, the top-one country with IPv6 deployment because all big players provided IPv6 connectivity. In today's operating systems, IPv6 will be used first if your computer sees "RA" packets (for "router advertisement" [1]) and can get an IPv6 address. This will be totally transparent. That's why many people think that they don't use IPv6 but they do!
