- Kube-proxy IP family will be determined by the nodeIP used by the proxier. The order of precedence is:
  1. the configured --bind-address if the bind address is not 0.0.0.0 or ::
  2. the primary IP from the Node object, if set.
  3. if no IP is found, NodeIP defaults to 127.0.0.1 and the IP family to IPv4 ([#91725](https://github.com/kubernetes/kubernetes/pull/91725), [@aojea](https://github.com/aojea)) [SIG Network]

If you have *path operations* using `response_model` that need to be allowed to return `None`, make it explicit in `response_model` using `Union[Something, None]`:
