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.

IPv4

72.5.240.64/26
66.151.69.64/26
178.32.71.224/28

The above can also be found as a text list here or as a JSON payload here.

IPv6

IPv6 is not officially supported at this time.

Retired Ranges

These iP ranges were previously used by SHR, but are no longer valid and MUST NOT be included in any whitelisting intended for SHR traffic.
