text: **DNS for OpenShift applications**
  Applications that are served by OpenShift are accessible by the router on ports 80/TCP and 
  443/TCP. The router uses a wildcard record to map all host names under a specific sub 
  domain to the same IP address without requiring a separate record for each name. This 
  process allows Red Hat OpenShift Container Platform to add applications with arbitrary 
  names if they are under that sub domain. 
  
  For example, a wildcard record for*.apps.example.com causes DNS name lookups for 
  app1.apps.example.com and app2.apps.example.com to both return the same IP address: 
  9.109.x.y. All traffic is forwarded to the OpenShift Infrastructure Nodes (Routers). The 
  Routers examine the HTTP headers of the queries and forward them to the correct 
  destination. 
  
  With a load-balancer host address of 9.109.x.y, the wildcard DNS record for 
  *.apps.example.com resolves IP address 9.109.x.y. 
  
  A simple DNS round-robin resolution can be used to spread traffic across infrastructure 
  nodes. 
  
  For production environments, it is recommended to have more advanced load balancing 
  capabilities to distribute the traffic among the OpenShift Routers. In those cases, an external 
  Load Balancer is used.
