I believe that there are some preparations that ISP providers need to make and changes that we will need to make to our web sites to make them IPv6 ready and capable.
It is expected that systems will try to use IPv6 first then IPv4 until eventually IPv4 is phased out.
But it wont be too far into the future before IPv6 addresses start getting handed out and I would just like to be sure that I am not going to loose business to my site as a result of not being IPv6 ready and capable.
Lunarpages will need to prepare themselves for IPv6 but web designers and developers don't need to do a thing unless you're sniffing for IP addresses. By the way, IPv6 addresses are already in wide use (use ipconfig in a command prompt in Windows to see your address if you have one). Also check
