- Fixing issue with Winkernel Proxier - IPV6 load balancer policies are missing when service is configured with ipFamilyPolicy: RequireDualStack ([#115615](https://github.com/kubernetes/kubernetes/pull/115615), [@princepereira](https://github.com/princepereira)) [SIG Network]

- Kubeadm: fixes a preflight check that can fail hostname construction in IPV6 setups ([#134590](https://github.com/kubernetes/kubernetes/pull/134590), [@liggitt](https://github.com/liggitt)) [SIG API Machinery, Auth, Cloud Provider, Cluster Lifecycle and Testing]

- Fixed a regression in kube-proxy where it might refuse to start if given
  single-stack IPv6 configuration options on a node that has both IPv4 and
  IPv6 IPs. ([#121008](https://github.com/kubernetes/kubernetes/pull/121008), [@danwinship](https://github.com/danwinship)) [SIG Network]

### Other (Cleanup or Flake)

- kube-proxy: HealthzBindAddress and MetricsBindAddress now support ipv6 addresses. ([#76320](https://github.com/kubernetes/kubernetes/pull/76320), [@JieJhih](https://github.com/JieJhih))

  * Report same Node IP as both internal and external. ([#45201](https://github.com/kubernetes/kubernetes/pull/45201), [@abrarshivani](https://github.com/abrarshivani))

  * Filter out IPV6 node addresses. ([#45181](https://github.com/kubernetes/kubernetes/pull/45181), [@BaluDontu](https://github.com/BaluDontu))

### OpenStack

* Fixed a bug in the OpenStack cloud provider where dual stack deployments (IPv4 and IPv6) did not work well when using kubenet as the network plugin. ([#59749](https://github.com/kubernetes/kubernetes/pull/59749), [@zioproto](https://github.com/zioproto))

     * The value is, e.g. http://localhost:9201 <br>
     * comment: <br>
     * The URL of the search engine HTTP endpoint.<br>
     * For IPv6 environments, use brackets around the IPv6 address (e.g., http://[::1]:9201)
     * @return The value of found property. (NotNull: if not found, exception but basically no way)
