I posted a question some time ago about an AWS Elastic ipv6 (AWS CLI Elastic IP, IPv6)
Basically i need to be able to change the ipv6 from one instance to another like an elastic ip. (Instances in High Availability)
The answer that i accepted was to use: aws ec2 assign-ipv6-addresses. It did work in fact for sometime, until i created two instances in different AZ (Availability Zone). For the ipv4, Elastic IP works great. But how can i do it with ipv6?
