=> Where does the IPv6 address come from? Unless you have
a v6 PDP context you can't get an IPv6 address.
if you use some tunneling technique, then you will get one. Tunnel broker,
as an example, will give the tunnel endpoint (UE) through the TSP session
the ipv6 address to use over the tunnel. It could also send the ipv6 prefix
in case the UE is a router/gateway to a personal network. Other tunnelling
techniques will give the Ipv6 address (6to4 or teredo based on the ipv4
address).
