How to verify a Google-GeminiNotebook request

  1. Run a reverse DNS lookup on the IP (host 192.0.2.1, with the IP from your log).
  2. Check the hostname ends in google.com or gae.googleusercontent.com.
  3. Run a forward lookup on that hostname and check it returns the same IP. Both steps must pass.

Google publishes IP lists for user-triggered fetchers but does not say which one applies to this fetcher.
