Ask your ISP?

Some tunnel brokers, such as sixxs, have a system for dynamic IP
addresses.

You can also use 6to4.

The most common setup is to have a "dual-stack" setup where the
machine is running IPv4 and IPv6 in parallel. But see
http://www.kfu.com/~nsayer/6to4/noipv4.html for instructions on how to
setup an IPv6-only network that has access to the IPv4 Internet, for
the hack value.

In a dual-stack setup, you run both simultaneously. With a tunnel, you
let IPv4 protocol 41 through on the "normal" interface with iptables
and do your IPv6 firewalling on the tunnel interface.
