Just as Per wrote,
I assume you have you mail and other services on you own domain-name,
and not on a sub-domain of your provider.
So mail/web/other-traffic goes to yourdomain.org

> From your current-isp you get an ip-address and on that adres you
terminate your IPv6-tunnel. Along with your tunnel you get an /64
network (ad if you want an extra /48 network)
Define all of your services of the addresses of that /48 network.

In case you switch to another provider, only the ipv4-address of your
tunnel changes, nothing else.

##
Actually, this is more related to managing your own domainname, but
since i started to use v6, i rather use names instead of addresses..
But even when you just use plain numbers, it is just adjusting your
tun-setup script with the ip-adres of your new provider, as the
addresses of your /48 remains the same.
