Tor supports IPv6 very
poorly and nobody cares much.
Lots of us care about IPv6. Our problem is finding *funders* who care enough
to pay for the time we need to implement this complex feature. But we're
working on a grant application right now:
It is discouraging to see so many small and large network operators not using IPv6. Why is this such a problem?
Tor relays don't automatically detect IPv6 addresses, and they don't test the reachability of IPv6 ORPorts. We are working on a grant application to add this support in Tor. (It's more complex than it seems, because we need to split the reachability checks per-ORPort, and add IPv6 extend support to Tor relays.)
Tor Project, please increase your #IPv6 awareness/outreach similar to how ARIN and the other RIRs try very hard to do.
I'll add an awareness objective to our grant application.
