 hi, i like to use IPv6 "temporary address with privacy extension". Which i
 get through dhcp on eth0. Well tor applications can only bind by IP not by
 interface. i cannot find howto bind programm to this temporary addresses
 without changing default routes. Is there some type of network interface
 or "pseudo" adresses to use as aliases? like, bind process to FC::2 and
 route this through => scope global temporary dynamic

  howto bind set torrc
 {{{
 OutboundBindIP
 }}}
  to interface for dynamic ips like => scope global temporary dynamic IPv6
 ?

Comment:

 We might end up using parts of this patch to *avoid* IPv6 address privacy
 on relays.

 IPv6 ?

 tor doesn't support OutboundBindAddress to interfaces.

 But you should be able to configure the default route at an OS level, and
 tor will use that for outbound connections.

 but might it would benefit for exit relays exitting traffic? could result
 in less punishment, less captchas for tor users.
  expect the IPv6 orport

 It might, but any sensible IPv6 address blocking service should be
 blocking at /56 or /64 (the host or local network block size), not /128
 (the individual device address). So it's unlikely to work for very long.

 Exit operators will get a rotating IPv6 address by default, if tor exits
 using the default route, and the default route uses IPv6 address privacy.
 (There's nothing we need to do in tor to enable this use case.)

 >  expect the IPv6 orport

 You're right, IPv6 address privacy is unhelpful for ORPorts, because they
 need to stay the same for at least 5 hours after they are published in the
 relay's descriptor. (After the descriptor is posted, it takes up to 1 hour
 for the authority reachability check, up to 1 hour for the consensus to be
 made, and up to 3 hours for all clients to get the consensus.)
