AWS Step Functions now supports IPv6 with dual-stack endpoints

AWS Step Functions adds supports for IPv6. You can now send IPV6 traffic to AWS Step Functions via new dual-stack IPv4 and IPv6 endpoints. AWS Step Functions is a visual workflow service that enables customers to build distributed applications, automate IT and business processes, and build data and machine learning pipelines using AWS services. This enhancement addresses the growing need for IP addresses as the internet continues to expand, providing a larger address space than the traditional IPv4 format.

With IPv6 support, organizations modernizing their applications can now build serverless workflows without being constrained by limited IPv4 address space. The new dual-stack endpoints support both IPv4 and IPv6 protocols while maintaining backwards compatibility with existing IPv4 endpoints. Step Functions also supports IPv6 connectivity through PrivateLink interface Virtual Private Cloud (VPC) endpoints, enabling you to access the service privately without traversing the public internet. This enables organizations operating in IPv6 environments to natively integrate with Step Functions without requiring complex translation mechanisms between IPv6 and IPv4.

IPv6 support for AWS Step Functions is now generally available in US East (Ohio), US East (N. Virginia), US West (Oregon), US West (N. California) as well as AWS GovCloud (US-East), and AWS GovCloud (US-West) Regions, where AWS Step Functions is available.
