I have a customer that needs me to able to forward DNS or change the users DNS via DHCP to the customers DNS on the fly. This is done if the user exceeds certain bandwidth limitations and allows the customer to redirect the user to a billing page or what not. DHCP can be used to do this but there is the lease time delay. I was thinking this could be done easier with my local DNS. That way I don't have to make any changes to DHCP and handle it much faster. I was hoping I could use forward-zones-recurse to forward certain users DNS to the customers DNS when required.
