AWS Elastic Beanstalk now supports IPv6 in dual stack configuration for Application and Network Load Balancers

AWS Elastic Beanstalk now supports dual-stack configuration for both Application Load Balancers (ALB) and Network Load Balancers (NLB), allowing environments to serve both IPv4 and IPv6 protocols. You can now set the IpAddressType option to "dualstack," and Elastic Beanstalk will automatically configure your load balancer with dual-stack support, creating both A and AAAA DNS records. You can seamlessly update existing IPv4 environments to dual-stack or revert back as needed.

This capability helps you reach users on IPv6-only networks while maintaining full IPv4 compatibility, supporting global accessibility requirements and IPv6 adoption mandates. The feature automatically handles DNS record management, simplifying IPv6 deployment for your applications and ensuring optimal performance for all users.

This feature is available in all AWS regions that support Elastic Beanstalk and Application and Network Load Balancers.

For detailed configuration steps, see the Elastic Beanstalk Developer Guide and Load Balancer documentation. Learn more about IPv6 networking in the Amazon VPC User Guide.
