this does not answer the op's question.  and 
dual stack assumes that you can get as much 
ipv4 space as needed to number your enture 
network. this assumption is no longer safe, 
at least without significant expense.

Hmm, I didn't see anywhere it said that.  All 
I saw was "We are looking into way we can 
gradually deploy IPv6 in our network…" and the 
subject "NAT64 for Dual Stacking!".

When he said "We are looking into way we can 
gradually deploy IPv6 in our network…" I did
what you said; assumed he had a functioning
IPv4 network and wanted to find a way to
deploy IPv6.

Folks…

We are looking into way we can gradually deploy IPv6 in our network…

Already we have it running and we have one Test Machine……. The challenge 
we are facing is that from that machine with IPv6 and from other 
Machines with IPv4 we can’t communicate in either direction..

IPv6 Machine just communicate with IPv6 only machines like wise IPv4 
Machines just communicate with IPv4 machines ….

A work around is to do NAT64 between the two subnets….

It seems the hardware (Cisco 2921 router with IOS Version 15.0) can’t do 
NAT64……..

From the internet it seems NAT64 runs on IOS-XE and IOS-CGSE which are 
Hardware dependent……..seems that we can’t upgrade IOS Version 15.0 to 
any the two which supports NAT64.

Before committing any expenses to acquire new router we want to reach 
out to the community for comments and advises….

Pls. review and advise.

Thank you…
