webpack-dev-server --port 3000 --hot
would allow the server to be accessed at:
http://10.0.1.4:3000 (my local IP).
In 1.8.0 accessing http://10.0.1.4:3000 no longer works.
Not sure if this has to do with webpack-dev-server or one of the dependencies.
I'm using node 0.12.2 and running OSX 10.10.2
1.8.0 appears to be defaulting to "localhost' now. You can open it up by passing the --host option.
webpack-dev-server --port 3000 --hot --host 0.0.0.0
