The pricing on IPv4 is now at USD 20/address so I am thinking we are forced to go the CGN route going forward. Of all the options, MAP-E appears to be the most elegant. Just add/remove some more headers on a packet and route it as normal. No need to invest in anything as our core routers can already do that. No worries about scale.

Actually, I think NAT64/DNS64/464XLAT is the best option, because as more IPv4 falls away, you are automatically translating less and going native IPv6 more. And there is nothing for you to "turn off" or migrate away from after all is said & done. Mark.
