We are now publishing our current IP address ranges in JSON format to help you manage network access controls and support other use cases. To view the current ranges, download the .json file using the download link ( ip-ranges.json ) . If you access this file programmatically, please make sure to ensure that the application downloads the file only after successfully verifying the TLS certificate presented by the server.
For more information, please read the blog, or visit the AWS IP Address Ranges documentation.
