Evidentially my site is working over IPv6 with just the ELB IPv6 enable and `AAAA` record. 

### ELB listener configuration

The load balancer does have configuration on how to route requests to EC2.  Here is a screenshot of the configuration for me where it clearly says it is doing so over IPv4:

### Testing tools

Last time I tried to test this, I saw failures over IPv6 with [a tool that shows screenshots of my website over both IPv4 and IPv6](https://screenshots.page/). I just tried the tool again and found that my site is available over IPv6, but it shows an error for IPv4.  It looks like the tool is not super reliable and errors from it are not always problems with your site.  I've also tried two other testing tools which show that my site is working properly (but which do not show screenshots:)
