title: Best practice for mobile app service domain
body: <p>We're developing a client-server game that communicates with our server in real time. During development we directed the client to the server's IP address directly.</p>
  
  <p>Moving forward to release, we'd like to switch the target server IP to a domain name.</p>
  
  <p>I'm looking for feedback whether we should use a sub-domain within our web-site main domain (say: server.mygame.com), or, setup a different domain for the game server (mygame-server.com).</p>
  
  <p>If there is no difference either way I'd love to get feedback on that as well.</p>
  
  <p>Thanks!</p>
