Can I browse an IPv6 Web site, if my ISP runs IPv4?
Yes, you can. You need some sort of transition mechanism to tunnel your IPv6 packets over the IPv4 infrastructure of your ISP. Two ways you can do this is to either set up 6 to 4 or configure a Tunnel Broker. You can find a list of public Tunnel Brokers at the IPv6 Portal Web site.
