miredo

I installed miredo and have IPv6 up and running it seems. I can ping6 hosts and download webpages with wget or my webbrowser when I specify IPv6 addresses, however whenever I specify a hostname that is offered over both IPv4 and IPv6 the browser picks the IPv4 address for the connection.

How can I change that and let the browser use IPv6 instead of IPv4 if available?

Googling around I found a hint that browsers will prefer IPv4 over IPv6 for 6to4/teredo tunnels, but so far I haven't found an explanation why or how to change that.

IPv6 is extremely important for the long-term health of the Internet. But is your Internet service provider providing IPv6 connectivity yet? Does your home network support it? Should you even care if you’re using IPv6 yet? Switching from IPv4 to IPv6 will give the Internet a much larger pool… >>> More
