Looker (Google Cloud core) instances with public or hybrid connections now support IP allowlists, which enhance security by ensuring that only traffic from specified IP addresses can access your instance. To connect to certain Google Cloud services, like Conversational Analytics or Connected Sheets, you can select an option to automatically allowlist the necessary IP ranges for those services. You can configure an IP allowlist for an existing instance by editing it in the Google Cloud console.

This feature will roll out to instances over the next week.
