When that system boots, it makes API calls to Dynect ensuring the

If the IP address changes, the records get automatically updated.

Sorry to resurrect an old thread, but I've jumped back into the DNS/hostname stuff again, and wanted to ask whether the IP address changes on the AWS side frequently?  Why wouldn't you just map i-177734b7c.example.com to the IP address on the interface?

Also, do you do a similar mapping for your internal host names?  e.g. would you map i-177734b7c.int.example.com to domU-12-84-39-3C-72-B2.compute-1.internal as well?

Thanks,
