CloudFront adds dual-stack IPv6 for private VPC origins
AWS now lets CloudFront reach private VPC origins over IPv6, removing the need to expose an ALB to the internet for end-to-end IPv6. There is no extra charge, and the feature covers 34 commercial Regions including sa-east-1. Dual-stack does not guarantee IPv6, as CloudFront picks the protocol per connection.

- Available in 34 commercial Regions, including sa-east-1
- IPv6-only for VPC origins is still not supported
- The private subnet needs a free IPv6 address for the service ENI
