IP Ranges for Production e-RS environment

We have JWKS endpoints that are hosted behind a firewall as per trust requirements, and we are enabling inbound requests for service that require access to it.

Please could you confirm what are the inbound IP ranges we would need to accept for the production environment of e-RS to access these JWKS endpoints? Also, if there is any official documentation that outlines this (as it is outlined for CIS2), please let us know this too.
