I want to use Route53 to give our organisation a standardised set of domain names for our dev environments (e.g. website2.theclient.development.com).
I can create a new sub domain in a Route53 hosted zone and associate it to the public IP or DNS for an EC2 instance. However, when an EC2 instance is shutdown and started up the public IP and DNS change and I have to update the Route53 A name.
I don't want to use a static IP for each EC2 instance. Is there another way to tackle this so that a domain name in a hosted zone is permanently associated with an EC2 instance?
