Kubernetes networking addresses four concerns:

- Containers within a Pod [use networking to communicate](/docs/concepts/services-networking/dns-pod-service/) via loopback.
|
||||
- Cluster networking provides communication between different Pods.

<li><i>ExternalName</i> - Maps the Service to the contents of the <code>externalName</code> field (e.g. <code>foo.bar.example.com</code>), by returning a <code>CNAME</code> record with its value. No proxying of any kind is set up. This type requires v1.7 or higher of <code>kube-dns</code>, or CoreDNS version 0.0.8 or higher.</li>

<p>Additionally, note that there are some use cases with Services that involve not defining a <code>selector</code> in the spec. A Service created without <code>selector</code> will also not create the corresponding Endpoints object. This allows users to manually map a Service to specific endpoints. Another possibility why there may be no selector is you are strictly using <code>type: ExternalName</code>.</p>

Kubernetes assumes that pods can communicate with other pods, regardless of which host they land on. Kubernetes gives every pod its own cluster-private IP address, so you do not need to explicitly create links between pods or map container ports to host ports. This means that containers within a Pod can all reach each other's ports on localhost, and all pods in a cluster can see each other without NAT. The rest of this document elaborates on how you can run reliable services on such a networking model.
