Amazon S3 now supports IPv6 for gateway and interface VPC endpoints

Amazon S3 now supports Internet Protocol version 6 (IPv6) addresses for AWS PrivateLink gateway and interface Virtual Private Cloud (VPC) endpoints.

The continued growth of the internet is exhausting available Internet Protocol version 4 (IPv4) addresses. IPv6 increases the number of available addresses by several orders of magnitude, and customers no longer need to manage overlapping address spaces in their VPCs. To get started with IPv6 connectivity on a new or existing S3 gateway or interface endpoint, configure IP address type for the endpoint to IPv6 or Dualstack. When enabled, Amazon S3 automatically updates the routing tables with IPv6 addresses for gateway endpoints and sets up an Elastic network interface (ENI) with IPv6 addresses for interface endpoints.

IPv6 support for VPC endpoints for Amazon S3 is now available in all AWS Commercial Regions and the AWS GovCloud (US) Regions, at no additional cost. You can set up IPv6 for new and existing VPC endpoints using the AWS Management Console, AWS CLI, AWS SDK, or AWS CloudFormation. To learn more, please refer to the service documentation.
