Because we use the Amazon EC2 cloud to dynamically instantiate load generation servers we don’t have a specific static IP address. However, we can provide the possible ranges for each EC2 data center or geographic location that we use. The only groups of ranges that we do not use are GovCloud, and Beijing. The list of ranges are no longer updated from Amazon’s blog post about EC2 public IP ranges.
Amazon now maintains the list of their EC2 public IP ranges in this JSON file: https://ip-ranges.amazonaws.com/ip-ranges.json
To make things easier we have added a list of our own that extracts the necessary IP ranges from Amazon’s JSON file. Please click a region below to see its list of IP ranges.
