  "scripts": {
    "dev": "webpack-dev-server --progress --colors --hot --content-base dist/ --open --config ./webpack.config.js --inline --watch --host :: --disableHostCheck",
  },
}

Expected Behavior

Webpack dev server starts, hosts server on all ip addresses (because of ::), then opens localhost to view the website

Actual Behavior

Webpack dev server starts http://[::]:8080/ in browser what is an invalid ip, what goes against the examples shown here: CLI: Host and Port Options

For Bugs; How can we reproduce the behavior?

Start the dev server using --host :: and --open
