Your organization may choose to do allow-listing with Redox based on your own security practices. Redox is hosted on AWS in the
us-east-1 region so if you choose to do allow-listing, we recommend that your organization allow-lists the IPs for the AMAZON and EC2 services in the
us-east-1 region. Learn more general information about allow-listing.
Our outbound IPs are assigned to us by AWS and updates to network architecture—including changes to our Virtual Private Cloud (VPC)—changes them. Our migration to AWS EKS changed our outbound IPs in 2021, which broke groups that allow-listed our specific outbound IPs at that time. We expect to make a similar change in 2022 as we prepare to go multi-region.
For more specifics, visit the AWS General Reference docs to download their list of IP address ranges. You can also find tools there for filtering and manipulating the file list.
