In the first case, the addresses are visible everywhere. In the
second
case, the destination address (in one form or another) is visible
everywhere. How is this suddenly a privacy issue?
Compare
V4user ---- NAT44 ---- v4server
And
V4user ---- NAT64 ---- v6server
If you embed the internal V4 address in the translated address, the
v6 servers will see it, while the v4 servers don't.
We must be talking about different things. What's the internal
translated address?
If NAT64 is deployed by ISPs then internal addresses are never seen by
NAT64 translators. The embedded v4 address only appears as a
destination address from the perspective of the IPv6 host, and even
with NAT44 the destination address is always sent as-is.
