Hm, the way I understand it is that the original BitTorrent protocol  
(not the original client, AFAIK) supported IPv6. However, the protocol  
was later streamlined and IPv6 support dropped, I think by other  
people. There's also the issue that you must choose one address to  
tell the tracker, and trackers may have their own opinions about IPv6  
addresses.

However, these days most BitTorrent clients use dynamic hash tables in  
addition to a centralized tracker and I believe IPv6 is used for/ 
through the DHT.
