Ok, terminated and restarted farm, and I think the DNS is acting right - I have mysql master and slave, and int-mysql-master goes to master, int-mysql goes to slave.
Don't know exactly what happened, why it works now and not last launch. But the Application/Edit DNS UI now shows the DNS being correct. Will post more info as I get it.
