This looks like a good place to start but just to note: MIAB default TTL is 30 minutes. So after making change in NSD and restarting service you will need to wait AT LEAST that amount of time before changes take affect.
Thanks for the link. The commands at the bottom of that page don’t seem applicable to what MIAB is running. There’s no nsdc, and those parameters don’t work with nsd.
I’ve been struggling with this for several weeks and any changes I’ve made just aren’t showing up after waiting an hour, a day, a week.
