Facebook uses IPv6 virtually everywhere. They have NAT for ipv4 in dual stack (usually only on certain desktop machines), but not for IPv6 as that defeats the usefulness of it.
virtually all the datacentre is exclusively IPv6. they kinda have NAT in the sense that all the web proxies at the edge terminate the IP connections with the outside world, but thats higher up the stack rather than on the IP level.
However I never dealt with the edge stuff, as that was far away from what I was doing.
