AWS – Amazon ECR adds support for Internet Protocol version 6 (IPv6)

Amazon Elastic Container Registry (ECR) announces IPv6 support for API and Docker/OCI endpoints for both ECR and ECR Public. This makes it easier to standardize on IPv6 and remove IP address scalability limitations for your container build, deployment, and orchestration infrastructure.

With today’s launch, you can pull your private or public ECR images via the AWS SDK or Docker/OCI CLI using ECR’s new dual-stack endpoints which support both IPv4 and IPv6. When you make a request to an ECR dual-stack endpoint, the endpoint resolves to an IPv4 or an IPv6 address, depending on the protocol used by your network and client. This helps you meet IPv6 compliance requirements, and modernize your applications without expensive network address translation between IPv4 and IPv6 addresses.

ECR’s new dual-stack endpoints are generally available in all AWS commercial and AWS GovCloud (US) regions at no additional cost. Currently, ECR’s dual-stack endpoints do not serve AWS PrivateLink traffic originating from your Amazon Virtual Private Cloud (VPC). To get started with ECR IPv6, visit ECR documentation or ECR Public documentation.
