Application Load Balancer (ALB) and Network Load Balancer (NLB) now support registering instances as targets when addressed by Internet Protocol Version 6 (IPv6) to simplify load balancer configuration. This launch enables you to directly register instances using IPv6 addresses as targets, removing the need to track individual IP addresses. The feature also enables the use of EC2 auto scaling groups with your target groups, which provides automatic registration of targets based on the scaling needs of your application.

IPv6 instance type targets support on ALB and NLB is available in all commercial AWS Regions, and in the AWS GovCloud (US) Regions. To learn more, please refer to the ALB documentation and NLB documentation.

12/1/23: A previous version of this post incorrectly stated that instances addressed by IPv6 are supported in Outposts. We have corrected this error in this version.
