To prevent potential blocking by your internal firewall or on-prem security services, it is recommended that you whitelist the below StackPath IP addresses. Whitelisting prevents 502 response codes being generated unexpectedly. You can also download the list of all blocks in .txt format from the attachment in this article at the bottom of the page.
StackPath IP Blocks are also available through the StackPath API. To learn how to pull this data from the API, please view this article.
