They are separated.  It's two different protocols, even though they are
similar in many aspects.

There are some projects trying to bridge that for single-stack IPv6
networks.  But I've concluded running dual-stack with both IPv4 and IPv6
is less error prone, as such a proxy solutions will not always work 100%
perfect.

The IPv4 addresses needs to be translated into a IPv6 addresses by a
local DNS service, and the proxy anyway need IPv4 access to reach the
IPv4 host.
