| Most Bittorrent clients, including [[http://www.utorrent.com|µTorrent]], [[http://azureus.sf.net|Azureus]], [[http://www.transmissionbt.com|Transmission]] and [[http://www.rasterbar.com/products/libtorrent/|libtorrent (Rasterbar)]] support exchanging data with both IPv4 and IPv6 peers at the same time today. [[http://libtorrent.rakshasa.no/|libtorrent (Rakshasa)]] (known for the famous rtorrent) does not support it yet, but there is a [[http://libtorrent.rakshasa.no/ticket/1111|patch]] available which will hopefully be integrated soon. | Most Bittorrent clients, including [[http://www.utorrent.com|µTorrent]], [[http://azureus.sf.net|Azureus]], [[http://www.transmissionbt.com|Transmission]] and [[http://www.rasterbar.com/products/libtorrent/|libtorrent (Rasterbar)]] support exchanging data with both IPv4 and IPv6 peers at the same time today.

| Unfortunately, to exchange data with IPv6 peers they have to find them first, which has been a problem for quite a while now. In general BitTorrent clients have three ways to aquire lists of possible IPv6-endpoints. | Unfortunately, to exchange data with IPv6 peers they have to find them first, which has been a problem for quite a while now.

| Historically IPv6 has been supported in trackers for a long time, since the original Tracker protocol exchanged IP address information as strings and was thus agnostic of the used protocol. To reduce the overhead a compressed format for exchanging peer data has been specificed in [[http://www.bittorrent.org/beps/bep_0023.html|BEP 23]]. IPv6-extensions to this protocol are specified in [[http://bittorrent.org/beps/bep_0007.html|BEP 7]]. | Historically IPv6 has been supported in trackers for a long time, since the original Tracker protocol exchanged IP address information as strings and was thus agnostic of the used protocol.

| Clients supporting this are µTorrent and Vuze, as well as all libtorrent (Rasterbar) based clients. The major exception is Transmission, which supports (as of Version 1.80) connecting to IPv6 peers, but not to IPv6 trackers. An explaination for this can be seen in their [[http://trac.transmissionbt.com/ticket/1731|bugtracker]]. | Clients supporting this are µTorrent and Vuze, as well as all libtorrent (Rasterbar) based clients.

An explaination for this can be seen in their [[http://trac.transmissionbt.com/ticket/1731|bugtracker]]. This has been somewhat fixed in version 2.20 to allow connections to IPv6-only trackers. Ubuntu has backported this change into 2.13 for Ubuntu 11.04 (Natty Narwhal). |

| While the software side was easy IPv6-support never got much traction in public trackers. Aside from projects like the [[http://www.sixxs.net/tools/tracker/|SixXS IPv6 Tracker]] and [[http://www.debian.org|Debian]] the only major tracker ever gaining IPv6 support was [[http://thepiratebay.org/blog/146|The Piratebay]]. Unfortunately they suffered from outages due to overload and network problems while being in major legal disputes at the same time. Today, TPB does not run trackers anymore. | While the software side was easy IPv6-support never got much traction in public trackers.
