CGNAT is for IPv4, so users can share IPs. It's pretty hard to use the internet without IPv4 access today, so it's not that much of a limitation.

But we do certainly plan to make IPv6 work on all our network services.

That’s… not what I said. If you want other people to host services (like to federate), it’s going to be pretty impossible for the vast majority of people to actually do it if you only allow IPv4 connections.

You cannot federate behind CGNAT, and most folks can only open ports over IPv6, because they don’t live in America where everyone can get their own public IPv4 address. This is a pretty big miss IMO.

Okay, I get what you're saying. Yes, hosting a PDS server behind NAT is a problem.

1. The expected scenario is that people would run PDS hosts on small VMs (Digital Ocean, Vultr, AWS, etc) where an IPv4 address is the default.

2. People running PDS hosts behind NAT would use a tunnel service of some kind (Cloudflare Tunnel, Tailscale Funnel, Ngrok, etc).

But IPv6 is something we do want to support, and it won't be a huge effort. It will just take a bit of time to get to it.
