IPv6 is the successor of the currently used Internet Protocol (IPv4, IP).

Bittornado, an improved version of the original Python-based Bittorrent client, supports IPv6. You need to add the following options to your normal parameters.

–ipv6_enabled 1 –ipv6_binds_v4 0

You need at least version 0.3.13 to use it.

Unfortunately, due to the way clients are registered in Bittorrent the tracker needs to be reachable with IPv6 as well. Currently the only available tracker software is the version of bttrack included in the Bittornado package.
