 -	Instances in the ALB’s target groups have to either have a single, fixed healthcheck port (“EC2 instance”-level healthcheck) or the healthcheck port for a target has to be the same as its application port (“Application instance”-level healthcheck) - you can't configure a per-target healthcheck port that is different than the application port.
 -	ALBs are VPC-only (they are not available in EC2 Classic)
 -	In a target group, if there is no healthy target, all requests are routed to all targets. For example, if you point a listener at a target group containing a single service that has a long initialization phase (during which the health checks would fail), requests will reach the service while it is still starting up.
+- Although it has been announced as coming soon, [ALBs do not presently support IPv6.](https://aws.amazon.com/about-aws/whats-new/2016/12/announcing-internet-protocol-version-6-support-for-ec2-instances-in-amazon-virtual-private-cloud/) Even if the ALB is launched in an IPv6-enabled VPC and subnet, it will only have IPv4 addressing.
