Amazon RDS now supports IPv6 for publicly accessible databases, allowing dual-stack connectivity with IPv4. This update helps users scale applications beyond IPv4 limits and facilitates a smoother transition to IPv6. The feature is available in all AWS regions that support IPv6 for private databases.

Amazon CloudFront has enhanced its IPv6 capabilities by introducing support for IPv6 origins, allowing for end-to-end IPv6 content delivery to origin servers. This update helps customers meet their IPv6 adoption requirements and improves network performance while alleviating concerns about IPv4 address exhaustion. Users can configure their origins to use IPv4-only, IPv6-only, or dual-stack connectivity in all supported AWS Commercial Regions, except for Amazon S3 and VPC origins.
