If you install a dhcp-v6 on there, sure.

No. This box does route advertisements only, I believe.

I was tempted to buy one recently to check out what exactly is
supported. I might still do that :)

Well, DHCPv6 is not very common yet. Most routers will do
route-advertisements. We even got Mikrotik to support the advertisement
of nameservers via rdnssd, which actually also make that a fully usually
auto-configuration then.

I spoke to AVM at CeBIT, and they are planning on doing DHCPv6 for the
Fritz! box family, but it's not in there yet. Currently it's
route-advertisements only.

Also be aware, that you can't use DHCPv6 only. You need
route-advertisements, too, because DHCPv6 doesn't set a default gateway.
