title: Is IP for maps.googleapis.com keeps changing or Fixed
body: <p>We have an Internal Server on which we want to use GEOCODING and accessing the URL from site <code>maps.googleapis.com</code>. Now we need Firewall Rules to allow the Internal Server to access <code>maps.googleapis.com</code> and have got 3 different IPs from different DNS Server which is OK. </p>
  
  <p>Now if we get these Firewall Rules done, then can google change the IPs which resolve to <code>maps.googleapis.com</code> quite frequently.
  Please advise.</p>
