Release: App Runner expands support for IPv6 compatibility on August 27, 2025

AWS App Runner expands support for IPv6 compatibility.

Release date: August 27, 2025

Changes

This release expands IPv6 support for AWS App Runner services by providing the dual-stack configuration option. Previously, App Runner support for IPv6 only included incoming traffic through public endpoints.

Starting with this release, you can use the dualstack option to configure incoming and outgoing network traffic to support IPv6 through both public and private endpoints. With this new release App Runner defaults outgoing public traffic to dual stack when you create a new service or when you deploy an update to an existing service.

For more information about how to manage dual-stack support for your App Runner service, see Networking with App Runner in the AWS App Runner Developer Guide.
