legacy/trac#17281 suggests that an IPv6-only client should be able to bootstrap by setting some flags in torrc. I've done: ``` ClientUseIPv4 0 ClientUseIPv6 1 ``` But, most clients are not *always* IPv4-only or IPv6-only. In particular, i tend to move my laptop between networks that have different properties (i'm writing this from a v6-only network). I shouldn't have to fiddle with my torrc to make tor work. it should be able to auto-detect this situation and do the right thing automatically.
