Description

Standalone Linodes have the option to set Reverse DNS (RDNS / PTR record on the IP address).

For LKE: While the underlying Linodes in a LKE cluster is still accessible (and we can set PTR record on the Linodes there), this won't survive a node recycle action.

Would it be possible to declare the desired PTR setting for all nodes in a LKE cluster? This would allow any node to send emails with the correct PTR setting, even if the nodes are recycled.

Research direction

Start by reviewing how LKE cluster nodes are created and recycled, focusing on where Linode node IPs become available for configuration. Define how a cluster-level PTR or RDNS setting would be declared and verify that the setting is reapplied after node recycle actions, so newly created nodes retain the desired reverse-DNS behavior.
