Within docker container can we get the host ip and the random ports allotted

Within docker container can we get the host ip and the random ports allotted for the ports exposed . The use case is to send a serf event to join the cluster with the host ip and random port allotted by docker daemon so that the load balancer can update itself. I like to send the event from within the container with these details without any dependency on the host machine
