    - When upgrading from previous releases, issues will arise with public IPs if multiple clusters share the same resource group. To solve these problems, make the following changes to the cluster:
Recreate the relevant LoadBalancer services, or add a new tag 'kubernetes-cluster-name: <cluster-name>' manually for existing public IPs.

	return allErrs
}

// validatePodIPs validates IPs in pod status
func validatePodIPs(pod *core.Pod) field.ErrorList {
	allErrs := field.ErrorList{}

	podIPsField := field.NewPath("status", "podIPs")

	// all PodIPs must be valid IPs
	for i, podIP := range pod.Status.PodIPs {

- Add --permit-address-sharing flag to `kube-apiserver` to listen with `SO_REUSEADDR`. While allowing to listen on wildcard IPs like 0.0.0.0 and specific IPs in parallel, it avoids waiting for the kernel to release socket in `TIME_WAIT` state, and hence, considerably reducing `kube-apiserver` restart times under certain conditions. ([#93861](https://github.com/kubernetes/kubernetes/pull/93861),...

- Kubelet should now more reliably report the same primary node IP even if the set of node IPs reported by the CloudProvider changes. ([#79391](https://github.com/kubernetes/kubernetes/pull/79391), [@danwinship](https://github.com/danwinship))

  * GCE installs will now avoid IP masquerade for all RFC-1918 IP blocks, rather than just 10.0.0.0/8. This means that clusters can be created in 192.168.0.0./16 and 172.16.0.0/12 while preserving the container IPs (which would be lost before). ([#46473](https://github.com/kubernetes/kubernetes/pull/46473), [@thockin](https://github.com/thockin))

- The `CloudDualStackNodeIPs` feature is now `beta`, meaning that when using
  an external cloud provider that has been updated to support the feature,
  you can pass comma-separated dual-stack `--node-ips` to `kubelet` and have
  the cloud provider take both IPs into account. ([#120275](https://github.com/kubernetes/kubernetes/pull/120275), [@danwinship](https://github.com/danwinship))

* Fixed bug in AWS provider to handle multiple IPs when using more than 1 network interface per ec2 instance. ([#50112](https://github.com/kubernetes/kubernetes/pull/50112), [@jlz27](https://github.com/jlz27))
