virtualbox 5.1.2 r108956

docker run -it --net=host edib/elixir-phoenix-dev /bin/bash
input ip address in container

wish to see the same ip as host network interface eth0

host ip is 192.168.1.55, container ip is 192.168.65.xx, here is the screenshot

docker run -it edib/elixir-phoenix-dev /bin/bash
in container run 
telnet to 172.17.0.1 8888

8888 is my host port, listening for http request, screenshot

container telnet 172.17.0.1 failed, but  ping 172.17.0.1 runs ok

running container can telnet to host port, it runs ok under linux docker.
