Amazon S3 Express One Zone now supports Internet Protocol version 6 (IPv6)

Posted on: Nov 10, 2025

Amazon S3 Express One Zone now supports Internet Protocol version 6 (IPv6) addresses for gateway Virtual Private Cloud (VPC) endpoints. S3 Express One Zone is a high-performance storage class designed for latency-sensitive applications.

Organizations are adopting IPv6 networks to mitigate IPv4 address exhaustion in their private networks or to comply with regulatory requirements. You can now access your data in S3 Express One Zone over IPv6 or DualStack VPC endpoints. You don't need additional infrastructure to handle IPv6 to IPv4 address translation.

S3 Express One Zone support for IPv6 is available in all AWS Regions where the storage class is available 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 get started using IPv6 on S3 Express One Zone, visit the S3 User Guide.
