IP ranges to use for whitelisting

We have a couple of services running on render that need to access a database that is hosted on Google Cloud SQL. For production, we’d like to button up the incoming connections that this DB can accept, and limit it to a whitelist of IP blocks.

Can you provide IP ranges that render services can be hosted on that we can use for this purpose?

Unfortunately, we don’t have a static set of IP address for allowlists. Other users have used Quotaguard to achieve this.
