Re: [opensuse] IPV6

Has someone set-up ipv6 over ipv4 with opensuse.

Not exactly ;-)

Do you need freenet6 for this. Or can you get a ipv6 also elsewhere so you get an assigned slice?

There a several ways of tunneling IPv6 over IPv4 (like 6over4, ISATAP IPv6 over GRE, Teredo tunnel, etc.). If you want to use 6over4 encapsulation, you can use the "sit0" interface, for example.
