      Description of problem:

         One dns pod out of 7 is resolving svchostname with wrong IP address, whereas all other pods are resolving correctly.

      Version-Release number of selected component (if applicable):

          Version- 4.12.37
         

      Actual results:

          when we try to resolve service hostname via dns-pod running on worker2, we are getting wrong IP, which doesn't exist in cluster.

      Expected results:

          We expect to get correct service IP of the application.

      Additional info:

      When pod running on worker2 tries nslookup svc hostname, we are getting wrong IP, whereas when we do nslookup from pod running on any other node, we are getting right IP of service.
