[AfrIPv6-Discuss] NAT64 for Dual Stacking!

[John Hay]

Hi Fabian,

Our approach was to deploy dual stack, so every router, server and host
have an IPv6 and an IPv4 address. So if something wants to communicate with
another device that have an IPv6 address, it will use its IPv6 address as
the source. If it wants to communicate with a device that have an IPv4
address, it will use its IPv4 address as the source. If it wants to
communicate with a device that have both IPv6 and IPv4 addresses, it
depends on the OS what is preferred.

That way we do not need NAT64. We will phase out IPv4 when it is not needed
anymore for internet or local communication.

Regards

John
