Grafana IP addresses

We are using Hosted Grafana instance, and own Prometheus as data source.
We would like to restrict access to the Prometheus server only from Grafana.
Which IP’s we can add to the firewall in order to Grafana successfully get metrics from Prometheus?

Thank you.

We’re in the process of setting up docs for Hosted Grafana, in the meantime this maybe answers your question?

Those lists are always updated with IP addresses of the nodes on our clusters that might be running Hosted Grafana instances.
