74.125.215.96/27Verify a Google-GeminiNotebook request
For Google-GeminiNotebook, compare the source IP from your trusted edge or server against Google’s current published prefixes.
Test one CIDR in Python (replace REQUEST_IP)
python3 -c 'import ipaddress; print(ipaddress.ip_address("REQUEST_IP") in ipaddress.ip_network("2001:4860:4801:4004::/64"))'Test every current prefix in the vendor feed and re-fetch it regularly. This cached snapshot is evidence of publication, not a permanent firewall list.
Control Google-GeminiNotebook with robots.txt
Google-GeminiNotebook is user-triggered. Google's controls may differ from automated crawling, so do not assume a robots.txt block is an authentication boundary.
