If created a service using an externalName pointing to some external service.

apiVersion: v1
kind: Service
metadata:
  name: test
spec:
  type: ExternalName
  externalName: google.com

When I now try to do a DNS lookup it doesn't return anything useful:

# dig test.development.svc.cluster.local.

; <<>> DiG 9.9.5-9+deb8u15-Debian <<>> test.development.svc.cluster.local.
;; global options: +cmd

If I query explicitly for type CNAME I get a response:

# dig -t CNAME test.development.svc.cluster.local.

; <<>> DiG 9.9.5-9+deb8u15-Debian <<>> -t CNAME test.development.svc.cluster.local.

If I change the Service to point to some other cluster internal service, I get the following expected result of an IP address:

# dig dogstatsdport.development.svc.cluster.local

; <<>> DiG 9.9.5-9+deb8u15-Debian <<>> dogstatsdport.development.svc.cluster.local

dogstatsdport.default.svc.cluster.local. 30 IN A 100.68.195.103

What is missing/wrong here? And how do I get the external record to resolve?

Cluster is currently running on Kubernetes 1.8.12, set up with kops 1.9.0.
