        er... what part of dual-stack didn't you understand?
        dual-stack consumes exactly the same number of v4 and v6 addresses.
        
        if you expect to dual-stack everything - you need to look again.
        either you are going to need:

        lots more IPv4 space

        stealing ports to mux addresses

        run straight-up native IPv6 - no IPv4 (unless you need to talk to 
        a v4-only host - then use IVI or similar..)

        imho - the path through the woods is an IVI-like solution.
