Tor and IPv6 exit nodes

Question

I use Windows and created my own program in which I use tor.exe. Only I need an exit node with IPv6. How do I configure torrc for this?

Answer 1

According to the manual, you can set:

PreferIPv6

Tells exits that, if a host has both an IPv4 and an IPv6 address, we would prefer to connect to it via IPv6. (IPv4 is the default.)

There is also:

IPv6Only

If the address is absent, or resolves to both an IPv4 and an IPv6 address, only listen to the IPv6 address.

This second one is a little vague, so I have no idea if it will do anything.
