- 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.

- This PR sets the --cluster-dns flag value to kube-dns service IP whether or not NodeLocal DNSCache is enabled. NodeLocal DNSCache will listen on both the link-local as well as the service IP. ([#84383](https://github.com/kubernetes/kubernetes/pull/84383), [@prameshj](https://github.com/prameshj))
- kube-dns add-on:

* Implement alpha version of PreferAvoidPods ([#20699](https://github.com/kubernetes/kubernetes/pull/20699), [@jiangyaoguo](https://github.com/jiangyaoguo))
* Retry when apiserver fails to listen on insecure port ([#28797](https://github.com/kubernetes/kubernetes/pull/28797), [@aaronlevy](https://github.com/aaronlevy))

* You can now have services that listen on the same host ports on different interfaces by specifying `--nodeport-addresses`. ([#62003](https://github.com/kubernetes/kubernetes/pull/62003), [@m1093782566](https://github.com/m1093782566))
* Added port-forward examples for service
