I can only assume that it is less than 10mbit in most cases, this looking at AMS-IX traffic graphs[1] and the ones from SixXS[2], the latter being almost quite a large bit of the AMS-IX traffic graphs (even has the same forms, which is quite funny). As AMS-IX is only doing 50mbit on peek time, when Teredo/6to4 traffic is more than 10mbit it would be more amazing than Mars[3]. Of course this is a bit of guess work and Teredo/6to4 traffic might partially avoid IX's or show up as IPv4 there. It would be fun to get an analysis of a heavy box though. But I can only assume that the usages are primarily: NNTP, bit of HTTP, SMTP and IRC. > I've just observed my Bittorrent client (Azureus) doing what I assume is > DHT (Distributed Hash Table) stuff over IPv6. > > The concern I have is that it's doing stuff from my 6to4 address to > 'native' v6 addresses, and Teredo addresses - which would produce a > higher load on the public relays for those protocols (probably). If you don't want or can't handle the traffic then either: - limit how far your 6to4 relay announces itself in BGP - don't run it and other similar options. This is btw why I am not a big proponent of 6to4: as a network operator you don't have much control over the path taken for packets by 6to4 hosts, nor who uses the relay in your network. > ps.

Current IPv6 traffic levels are simply pathetic. For folks wanting to know which BitTorrent clients work over IPv6, please check: http://www.sixxs.net/tools/tracker/clients/ That system also has an IPv6-only tracker service where people can upload their files upto and it will be properly seeded for other folks to download.
