-When running the gate scripts in `tools/gate` locally, if you have not set proxy
-information in user's environment or profile then you will need to add your
-proxy information to
-`playbooks/vars/local-dev.yaml`.
+`10.23.0.0/16` encapsulates the range of addresses used by airshipctl
+development environment virtual machines, and `10.96.0.0/12` is the Kubernetes
+service CIDR.
 
-Apart from adding proxy information to playbook, we have to add proxy information
-to site definations documents. For ephemeral iso to pull docker images behind
-proxy, user-data section for ephemeral iso has to be updated in the below file
-`manifests/function/ephemeral/secret.yaml`.
+### DNS Configuration
 
-Add the following contents to the file in runcmd section

-```sh
-    - export http_proxy=http://username:password@host:port
-    - export https_proxy=$http_proxy
-    - export HTTP_PROXY=$http_proxy
-    - export HTTPS_PROXY=$http_proxy

+If you cannot reach the Google DNS servers from your local environment, add your
+DNS servers to
+`manifests/type/airship-core/shared/catalogues/common-networking.yaml` in place
+of the Google ones.
