Amazon CloudFront announces support for IPv6 origins

Amazon CloudFront expands its IPv6 capabilities by introducing support for IPv6 connectivity to origin servers, allowing customers to implement end-to-end IPv6 content delivery for their web applications. Support for IPv6 origins enables customers to send IPv6 traffic all the way to their origins, allowing them to meet their architectural and regulatory requirements for IPv6 adoption. End-to-end IPv6 support improves network performance for end users connecting over IPv6 networks, and also removes concerns for IPv4 address exhaustion for origin infrastructure.

Previously, CloudFront only supported IPv4 connectivity to origins, despite accepting IPv6 connections from end users. Customers using CloudFront can configure their custom origins to use IPv4-only (default), IPv6-only, or dual-stack connectivity. When using dual-stack, CloudFront will automatically choose between IPv4 and IPv6 addresses to ensure even distribution of traffic towards origin over both.

Customers can configure IPv6 origins in all supported AWS Commercial Regions. Customers can configure IPv6-only or dual-stack origins with CloudFront, excluding Amazon S3 and VPC origins. To learn more IPv6 support with CloudFront, visit the CloudFront documentation.
