How Will IPv6 affect you?

As an end user, it is unlikely that you will see much impact from the switch to IPv6. However, as a website owner there are more factors to consider.

IPv4 and IPv6 are essentially parallel networks so to exchange data between the two protocols requires special gateways.

While most Operating systems can support both, a lot of Routers and servers don't support it currently. The replacement of this hardware and corresponding software will obviously cost a lot of money which is why uptake of IPv6 has been slow.
