+## Dual Stack
+
+To use dual stack (IPv4 and IPv6) for your incoming public network configuration, set `ipAddressType` to `IpAddressType.DUAL_STACK`.
+
+```ts
+new apprunner.Service(this, 'Service', {
+  source: apprunner.Source.fromEcrPublic({
+    imageConfiguration: { port: 8000 },
+    imageIdentifier: 'public.ecr.aws/aws-containers/hello-app-runner:latest',
+  }),
+  ipAddressType: apprunner.IpAddressType.DUAL_STACK,
+});
+```
+
+**Note**: Currently, App Runner supports dual stack for only Public endpoint.
+Only IPv4 is supported for Private endpoint.
+If you update a service that's using dual-stack Public endpoint to a Private endpoint,
+your App Runner service will default to support only IPv4 for Private endpoint and fail
+to receive traffic originating from IPv6 endpoint.
+
 ## Secrets Manager
 
 To include environment variables integrated with AWS Secrets Manager, use the `environmentSecrets` attribute.
