Identify the state of IPv6 support in Tor

What works for IPv6 today? What doesn't? What's hard to configure?

  • Can clients use ipv6 to connect to Tor?
  • Can clients resolve Ipv6 addresses with Tor?
  • Does automapping to ipv6 addresses work?
  • Can we exit to ipv6?
  • Can bridges be IPv6-only? (no, I don't think so)
  • Can relays be IPv6 only? (no)

And many more.

We should ideally not only hand-check tehse issues, but write tests for some of them.

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
