I'm using 6to4 with my static IPv4 address. Some sites

fine. Unfortunately others don't seem to be working at all
(www.kame.net, ipv6.research.microsoft.com,
altavista.ipv6.digital.com.)

Is this likely to be due to some problem at my end or the 6to4 relay
I'm using? Here's a traceroute6:

Not every provider has necessarily a working 6to4 gateway set up and that 
means, you can't get there, because you don't get any traffic back.

I recommend using SixXS (http://www.sixxs.net) or Hurricane Electric 
(http://www.tunnelbroker.net / http://www.he.net) .

As it seems, that your IPv6 traffic hits the latter anyway pretty soon after it 
leaves your host, you might be better off with that.

Check out to whom you get the latency and get a tunnel from them or make your 
provider aware, that you want native IPv6.

Kind regards,
