title: How to check if DynDNS is working
body: <p>Newbie programmer here. I'm building an app for an API that requires an IP address for authentication. Basically, users have to send the API management their IPs and then each time a computer makes a request to their server, it verifies whether it's coming from a registered IP.</p>
  
  <p>Since I work in a number of different places and thus end up with different IPs, I thought it would be easiest to use DynDNS to establish a URL that points to whatever my current IP is and then send that URL to the API management. So my first question is if this approach would in fact work?</p>
  
  <p>Secondly, assuming this would work, I set up ben.dynalias.com and downloaded the DynDNS Updater client. It appears to be working: the updater says status: OK and displays my current IP. However, when I navigate to the URL (ben.dynalias.com) there's no response. Should this be the case? How can I tell if it's working?</p>
