-- Docker's host networking feature is not supported on Mac, even though the `docker run` command doesn't complain about
-  it.<br/>
-  This is due to the fact that the Docker daemon on Mac is running in a virtual machine, and not natively; hence, ports
-  are exposed on the VM and not of the host running it.<br/>
-  One way around it is port forwarding to localhost (the `-p` or `-P` options).
+- From inside a container, `localhost` and `127.0.0.1` will always refer to the container itself unless it is configured
+  to use the `host` networking feature.
+- One **cannot** reach containers directly via the network on Mac, even when started with the `--network=host` setting.

+  Docker Desktop runs the Engine in a virtual machine, not natively; hence, ports are exposed on the VM and not of the
+  host running Docker Desktop.<br/>
+  Refer [I cannot ping my containers][docker docs  i cannot ping my containers].
+
+  One can go around this limitation by:
+
+  - Forwarding ports to localhost (the `-p, --publish` or `-P, --publish-all` options).
+  - Using tools like [chipmk/docker-mac-net-connect].
