Step 3 of the external-dns → in-cluster bind migration: the client-visible cutover. The openforwarder resolvers stop reading the legacy VM and forward the k8s zones to the in-cluster bind-externaldns VIP (198.18.200.8), which external-dns now populates. - Repoint the fwd-k8s-syd1-au-unkin-net forwarder from the legacy VM anycast 198.18.19.20 to the in-cluster bind-externaldns VIP 198.18.200.8. - Add fwd-200-18-198-in-addr-arpa forwarding 200.18.198.in-addr.arpa to 198.18.200.8, closing the reverse-zone gap so PTR lookups for the k8s LB range resolve after cutover. - Refresh the header comment to describe the in-cluster upstream.
