The configuration steps to get tor running on an ipv6 only host is not clearly documented anywhere official.

FAQ - How do I use Tor from an IPv6 only host/computer?

Answer - You'll need to be using Tor version 0.2.8.x or newer and add the following two entries into your torrc.

ClientUseIPv4 0
ClientUseIPv6 1

In the torrc man page, the ClientUseIPv6 section can have this one line appended.

For IPv6 only hosts, you need to set ClientUseIPv4 to 0 to disable IPv4.

Thanks mutantmonkeey and gamambel on #tor for the solution and access to trac! :-)

There aren't many IPv6 users, or IPv6 guards, so as of 2018, Tor over IPv6 is less anonymous than Tor over IPv4.
Please add this information to the FAQ entry.

The default goes at the end of every man page entry. Please add your new sentence in the middle. And it might be worth saying "also set ClientUseIPv4 0".

Also, you've submitted pull requests for two different components on the same ticket. These components have different committers. Please open a separate ticket for each component.

Thanks for reviewing. What do you think about also adding:

You can review the IPv6 implemetation status at our IPv6Features wiki page.

known issues can be found with the ipv6 keyword.

I don't really mind.

But I'm not sure that most people would gain much from those pages.

Just added a commit, maybe they become more relevant in the future, or will be updated with more eyes on them.
