Starting today, AWS Lambda’s support for Lambda functions to access resources in dual-stack VPC (outbound connections) over IPv6 is available 6 additional AWS regions: Asia Pacific (Hyderabad), Asia Pacific (Melbourne), Europe (Spain), Europe (Zurich), Israel (Tel Aviv), and Middle East (UAE). 

With Lambda’s support for IPv6 for outbound connections in VPC, Lambda functions can access resources in dual-stack VPC over IPv6 and get virtually unlimited scale, using a simple function level switch. This enables you to scale your application without being constrained by the limited number of IPv4 addresses in your VPC, and to reduce costs by minimizing the need for translation mechanisms.

You can enable outbound access for new or existing Lambda functions to dual-stack VPC resources over IPv6 using the AWS Lambda API, AWS Management Console, AWS Command Line Interface (AWS CLI), AWS CloudFormation, AWS Serverless Application Model (AWS SAM), and AWS SDK. For more information on how to enable IPv6 access for Lambda functions in dual-stack VPC, see the Lambda documentation. To learn more about Lambda, see the Lambda developer guide.
