Yes.

Yes. That's a socket option which you can set just as you would set it using C 
(at least under Unix, under Windows: no idea).

No. That's an OS's job. You could, of course, implement a 6in4-tunnel using 
TUN interfaces, completely in Python. But I don't think that's what you want 
to do. And, anyway, your host OS would need IPv6 support for this to work. I 
wouldn't know how you'd go about implementing this on Windows, though.

> 4. If an IPv4 address is given, does it support this on a IPv6 network?

Depends on the OS. If the OS supports 6to4, then Python does too (because an 
IPv4-Adress is simply mapped to an IPv6-Network with a certain notation, look 
up the documentation for the 2001::-network on Wikipedia, for example). If 
the OS doesn't, Python doesn't either. This is also an OS job, not a Python 
job.
