### SIG Network

For 1.13, the areas of focus were in IPv6, DNS improvements and some smaller items:
CoreDNS is now the default cluster DNS passing all of the scale/resource usage tests

- In "large" clusters, kube-proxy in iptables mode will now sometimes
  leave unused rules in iptables for a while (up to `--iptables-sync-period`)
  before deleting them. This improves performance by not requiring it to
  check for stale rules on every sync. (In smaller clusters, it will still

- Kubelet: turn the KubeletConfiguration v1beta1 `ResolverConfig` field from a `string` to `*string`. ([#...

**Note**: This only impacts the cluster if the ServiceAccount admission plugin is used (most cluster should have this on by default as recommended in https://kubernetes.io/docs/reference/access-authn-authz/ad...
