AWS – Amazon CloudWatch Synthetics adds IPv6 support

CloudWatch Synthetics now allows canaries running in a VPC to make outbound requests to IPv6 endpoints allowing monitoring of IPv6-only and dual stack enabled endpoints over IPv6. You can also access CloudWatch Synthetics APIs over both IPv4 and IPv6 through new dual stack compatible regional endpoints. Additionally, PrivateLink access to Synthetics within VPCs is now available over IPv6 connections.

Using CloudWatch Synthetics, you can now monitor the availability and performance of websites or microservices accessible via IPv6 endpoints ensuring that end users can use the applications seamlessly irrespective of their network protocol. You can create IPv6 enabled canaries in your VPC using the CLI, CDK, CloudFormation, or the AWS console, and update existing VPC canaries to support dual stack connectivity without making any script changes. You can monitor endpoints external to your VPC by giving the canary internet access and configuring the VPC subnets appropriately. Now you can manage Synthetics resources in environments with IPv6-only networking policies, or access Synthetics APIs via IPv6 without traffic traversing the internet using PrivateLink helping meet security and regulatory requirements.

IPv6 support for Synthetics is available in all commercial regions where CloudWatch Synthetics is present at no additional cost to the users.
