# NodeLocal DNS

> * Kubernetes v1.17.4 and up
NodeLocal DNS is an additional component that can be deployed on each node to improve DNS performance. It is not a replacement for the `provider` parameter, you will still need to have one of the available DNS providers configured. See [Using NodeLocal DNSCache in Kubernetes clusters](https://kubernetes.io/docs/tasks/administer-cluster/nodelocaldns/) for more information on how NodeLocal DNS works.
## Configuring NodeLocal DNS
The `ip_address` parameter is used to configure what link-local IP address will be configured one each host to listen on, make sure this IP address is not already configured on the host.
```yaml
dns:
provider: coredns
nodelocal:
ip_address: "169.254.20.10"
```
