Silly uTorrent: "hostname not found" for IPv6-only tracker on stupid Windows Vista
uTorrent is a great graphical tool to activate Teredo IPv6 on Windows XP.
However, uTorrent on Windows Vista is quite silly: with the IPv6-only tracker tracker.sixxs.net, uTorrent says "hostname not found". Grrrr! And do remember: on Vista Teredo IPv6 is enabled by default, so IPv6 should work.
Probably uTorrent is using Vista's braindead name resolving, meaning: no AAAA lookups with Teredo IPv6.
Advice @ uTorrent developers: on Windows Vista, do an explicit AAAA lookup ... please!
