Maybe when you upgrade your router to one that cares about IPv6 it will work. Never say never. Also...

That's not going to last. The price of having an IPv4 address must go up over time since demand will continue to increase and it will (already is at some places such as Hetzner and other managed hosts) cost more than IPv6 which is usually a free address.
