hi there<br>
<br>
I think that the alternative for an authoritative DNS will be NSD<br>
instead of unbound.<br>
<br>
In my case I have ISPCONFIG for our first DNS (ispconfig+bind), and then<br>
rsync every few minutes to my second DNS (the NSD one) and "slightly"<br>
transform the configuration from bind to nsd.<br>
<br>
if you need more details you may write me directly. It is somehow easy.<br>
<br>
