IP Judge ipjudge.org
Gemini region check
Whether your exit is on Google’s Gemini lists (the web app and the API are judged separately), and whether gemini.google.com responds.
Google offers no public way to read the IP it sees, so Gemini is judged by the exit that opened this site, plus a reachability test. Google prefers IPv6: if your IPv6 exit is in another region, Gemini may see that one — the checks below flag it.

Proxies often route by domain: the IP that opened this site is not necessarily the one Claude or ChatGPT sees. The first two checks ask claude.ai and chatgpt.com directly.
“Region not supported” — figure out which layer first
Gemini on the web and the Gemini API use two different region lists, so a browser that works does not mean the API will. Confirm the exit is on the right list first, then look at IP type — a datacenter IP in a supported region can still be asked for extra verification.

Where is Gemini not available?
On Google’s list (checked 30 September 2026) mainland China is Workspace-only, so personal accounts don’t count. Hong Kong, Macau and Taiwan are listed. The list changes; see Google’s help page.
The web app works, but the API or AI Studio says my region isn’t supported
Google publishes one list for the web app / mobile app and another for the Gemini API / AI Studio. As of 1 October 2026 Hong Kong and Macau are on the web list but not on the API list, so the Gemini card shows both. If your code runs on a server, run curl ipjudge.org there to see its exit.
My exit is in a supported region but Gemini still refuses
Often IPv6 takes another route that skips the proxy — see the IPv6 check. The Google account’s own country can also matter; that we can’t see.

Is the residential IP you bought really a home line?
The check looks at the IP itself, not the seller’s description: type, native or broadcast, blocklists and proxy flags, each with its evidence. For several IPs:
