text: **4.2 OpenShift container platform networking**
  
  While installing all the prerequisites that are needed to deploy the OpenShift Container 
  Platform configuration, all of the nodes must include internet access to register each node 
  and install every dependency that is left. 
  
  During the installation process, an internal network is configured. To make this process 
  possible, a virtual switch is installed and configured automatically. This switch ensures that 
  the internal network is forwarded from the public network. 
  
  OpenShift Container Platform features a built-in DNS to resolve the hosts that are created 
  internally. This DNS manages the port forwarding for the public IP into the internal network, 
  such as for resolving the internal services IP addresses. 
  
  When a service is created, a new IP address can be assigned to it. If this service is deleted 
  and re-created, a new IP address can be assigned by default or the cloud administrator can 
  configure a specific IP address and host name on it. 
  
  This section provides an overview of the main OpenShift software-defined networking (SDN) 
  solutions and describes the traffic flow among pods that are inside the cluster. Also discussed 
  is how these pods communicate to destinations that are outside of the cluster. 
  
  **4.2.1 OpenShift networking overview**
  
  OpenShift Networking features two main components: the OpenShift Software Defined 
  Network plug-in to handle the communication within the cluster and the OpenShift Router 
  plug-in to handle the inbound and outbound traffic that is destined to services in the cluster.
