2007. Half of IPv6's lifetime ago. It came out of an ARIN PPML thread titled "The myth of IPv6-IPv4 interoperation."
On one side of the argument, folks saying that the need to manage two configurations impairs IPv6's deployment.
On the other, an individual  whose thesis was the IPv6 could not have been designed to be backwards compatible
with IPv4 in a way that required no new configuration, just incremental, backward-compatible software upgrades.

Why did you choose this route, instead of encapsulating the packet with the extended address into an IPv4 packet ?
