You can now subscribe to Amazon Simple Notification Service (SNS) notifications for changes of AWS' IP address ranges. We publish the IP address ranges for AWS and specific services, like Amazon Elastic Compute Cloud (EC2), Amazon CloudFront, and Amazon Route 53 in a JSON file. You can use these ranges to update your firewalls or other configurations. Now you can use this Amazon SNS notification to automate the updates. For more information, see http://docs.aws.amazon.com/general/latest/gr/aws-ip-ranges.html.
