I read the federal government’s Zero-Trust Memo so you don’t have to

Meh. OMB also mandated moving to IPv6 more than a decade ago: https://www.cio.gov/assets/resources/internet-protocol-versi...

Nobody cares. It just gets postponed forever.

The memo you're linking to was recently updated and did have force. The DOD, one of the largest federal agencies, issued its own memo with similar deadlines, and this & others have had the result of jumpstarting IPv6 / dual stack support for all of the major clouds & Kubernetes.

If FedRAMP qualification is tied to IPv6 support, you'll see every major contractor and cloud provider support it promptly.

If you look at the recent updates for cloud providers - AWS and GCP support for IPv6, Kubernetes going dual stack by default - you can see that this memo had a substantial impact.

Sometimes these things take time, but in this case, the recent memo you link to lit a fire under everyone.

Yeah AWS has added a lot of ipv6 support recently, like ipv6 only subnets so you can actually benefit from using ipv6. Waiting for rds support though.

Azure is so far behind on this it's silly.
