I am reading about ipv6 nat. I guess it's possible but discouraged?

This contention point confuses me. I consistently get downvoted for this opinion, and I've seen contrarian voices online, but I have yet to meet an actual datacenter network admin who disagrees with me.

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.

I am one, also disagree with you. Ipv6 nat is possible. I dont find nat particularly useful inside a network and dont use it unless strictly required to solve a problem like shared internet access or overlapping IP addresses. Isolation is best handled with separate physical networks, vlan or firewalls.

It's totally possible and it's totally discouraged. We are not the internet police on HN, and neither is the IETF. If you want to do weird stuff on your own network, you can and you get to keep both pieces.
