title: Can I use domain AND port in a routing group in Laravel?
body: <p>Is there any way to bind routes to an port?
  I am using Laravel 5.5</p>
  
  <pre><code>Route::domain('example.org:8080')-&gt;group(function() {... some routes ...})
  Route::domain('example.org')-&gt;group(function() {... other routes ...})
  </code></pre>
  
  <p>I already tried to use a route pattern in the RouteServiceProvider.
  But it only allows me to route by the complete domain.</p>
  
  <pre><code>class RouteServiceProvider extends ServiceProvider
  {
    ...
    public function boot()
    {
      // allow complete domains
      \Route::pattern('domain', '.+');
    }
    ...
  }
  </code></pre>
