Hi,

I'm trying to understand the intent and use-cases for cluster IP. From the 
documentation it seems like ClusterIP is meant to be only within the cluster. 
Does that also include the host on which a pod(s) are scheduled or is it 
strictly from pod-to-pod?

Also, from my understanding of the internal workings of ClusterIP; you can 
reach the backend endpoints of the services because of the DNAT rules destined 
to ClusterIP. Is that understanding right? I'm not able to reach the backend 
pods over ClusterIP from the host(the same thing works from the pod). I see 
these rules, but I'm not sure if there any other requirement for these 
pre-routing rules to be hit.

Thanks,
Divya
