Verify a Google-CloudVertexBot request

For Google-CloudVertexBot, 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("192.178.4.0/27"))'

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-CloudVertexBot with robots.txt

Google documents crawler controls for this bot family. Robots.txt can direct cooperative crawling, but it cannot prove that a request is authentic.

Aiola Analytics

See every Google-CloudVertexBot visit on your site

Aiola tracks 70 AI, search and link-preview crawlers next to your human traffic. See when Google-CloudVertexBot arrives, which pages it requests and how that changes over time. Hosted Analytics needs Pro or a trial.

Common questions

Match the case-insensitive token “Google-CloudVertexBot” in the User-Agent header. A matching header alone does not authenticate the sender.

Google publishes an IP range list, and this page snapshots 317 CIDR prefixes fetched on 2026-10-23. Match the source IP against the current vendor feed before trusting it.

Use a specific “Google-CloudVertexBot” group for crawler-specific rules. Review the policy details below: robots.txt is a request to compliant crawlers, not an access-control system.
