If you must use your ISP name servers, you must configure a forward-zone option for the root zone (.) pointing to them, and then you need to detect when the ISP name server address(es) change(s) and use the unbound-control forward_remove and forward_add commands to change the settings. (My ISPs have rarely, if ever, changed their DNS server addresses, there is hardly ever a reason to do that. I would just set up the forward-zone and handle DNS changes manually, maybe write a script to translate resolv.conf nameservers to unbound-control commands.)
How do you tell unbound to go to this public root zone?
Is this root zone an unbound internal hard codded function?
