I believe that I have, here is a snippet of the config file. Still using the ipv4 address for HA url for the ipv6 config...
Thank you for helping!

John,
That is correct. If both servers are sharing the same database and
are both configured for HA, then you may want to look at disabling
lease synchronization as described here:

I set up a postgresql backend db for the databases and in doing so I am now using the same pools for both servers instead of splitting the pool between them. I did this because each server will register it lease within the database so and each server checks the database to verify that the ip is available before it offers it? At lease that is my understanding.
