[Pdns-users] listen on net iface

PS: This sound like you want to run PDNS in an active-standby HA-setup with a "hot" standby. But if this PDNS instance has SLAVE and MASTER zones configure, it will peform slave-checks and master-checks and writes into the backend (which may be a database). To avoid issues with multiple PDNS processes writing into a single DB you can configure your HA manager to start PDNS only once the floating IP is migrated to the standby server.
