This shouldn't be mistaken for an anti-IPv6 post. There's also some steps you have to go through to enable IPv6 on your VPS networks, and there's still stuff like GitHub not handling IPv6. So, much as we need to migrate, we still have to support IPv4 connectivity for the foreseeable future.

Shoutout to Hacker News for having IPv6 support!

And virtually everything inside of AWS still requires IPv4 so even if you have zero need to reach out to WAN, if you need any number of private AWS endpoints, you're going to be allocating some ipv4 blocks to your VPC :(.
