Do you have a migration plan for IPv6 yet? (part 2 of 2)

Chart from http://bgp.potaroo.net/v6/as2.0/index.html    Over the past few years, the growth of IPv6 has increased greatly.

Most end-users today get one IP address, which is shared between multiple machines using a Network Address Translation (NAT) router. In IPv6, each user gets an address block – a /64 – of address space. This is great news, because end-to-end application on the Internet will work much better, and there will be no NAT in the way. A /64 is a huge amount of space –...
