 You can also see [an example of using `kubeconfig` in the `./extras`](./extras/example-with-kubeconfig.yaml).
 
+### Note on DNS
+
+Note, that on top of resolving the other pods, all instances can also try to resolve arbitrary DNS. This allows you to test your DNS setup.
+
+From `--help`:
+
+```sh
+--host-to-resolve=      A host to attempt dns resolve on (space delimited) [$HOSTS_TO_RESOLVE]
+```
+
+So in order to test two domains, we could add an extra env var to the example above:
+
+```yaml
+            - name: HOSTS_TO_RESOLVE
+              value: "www.bloomberg.com one.two.three"
+```
+
+and `goldpinger` should show something like this:

+![screenshot-DNS-resolution](./extras/dns-screenshot.png)
