Some applications or clients need to know about SHR’s IPs for security and whitelisting purposes. This page is intended to be the definitive source of SHR’s current IP ranges.
We utilize Cloudflare in certain places within our application architecture. The IP addresses for Cloudflare’s public endpoints can be found here. These may also need to be whitelisted if you are blocking outbound communication at your firewall.
