Feature Request to Allow Dynamic Addition/Removal of Forwarders (similar to rndc addzone)[ISC-support #12719]
Originally submitted to BUGs as https://bugs.isc.org/Ticket/Display.html?id=35890
An ISC Support customer expressed surprise at the failure, after trying, and failing (but with side-effects) to add a zone of type "forward" using rndc addzone.
Per discussion with engineering at the time, addzone isn't intended to support addition of zone type forward AND forward zones aren't really traditionally zone-like so it does not work. The ARM is/was incorrect to suggest that it does.
Further information around this is available on bind-users: https://lists.isc.org/pipermail/bind-users/2016-November/098007.html
This feature is still wished-for.
