title: Ways to handle dynamic public IP address for AWS EC2?
body: <p>Recently I have successfully set up a Windows server SFTP server. I noticed that whenever I shut down my EC2 instance and re-run it, the public IP address will change.</p>
  <p>This is an issue for me as I key in the public IP address in my hardware settings and I do not wish to update the IP address every time the EC2 instance restart; especially when some of my hardware are miles away from my location!</p>
  <p>What kind of approach should I take to tackle this issue? I remember that dynamic DNS will resolve dynamic public IP address, will it work in this case?</p>
