IPv6/IPv4 Address Embedding
Due to the importance of IP and the significance of the changes made in IPv6, deployment of the newer version of the protocol will not occur all at once. A transition from IPv4 to IPv6 will be required. This transition requires careful planning. It is anticipated that the migration from IPv4 to IPv6 will take many years, as I mentioned earlier.
IPv6 is backward-compatible with IPv4 provided that you use special techniques. For example, to enable communication between islands of IPv6 devices connected by IPv4 networks, you may need to employ tunneling. To support IPv4/IPv6 compatibility, a scheme was developed to allow IPv4 addresses to be embedded within the IPv6 address structure. This method takes regular IPv4 addresses ...
