Verifying Google user-triggered fetchers

The user agent string Google-Site-Verification, FeedFetcher-Google … can be faked by anyone, and scrapers often pretend to be well-known bots to get past rate limits. Before you treat a request as Google user-triggered fetchers:

Check that the request IP is inside one of the prefixes above (the checker on this page does exactly that).
Load the list from its source on a schedule; do not hard-code it.
Allow the verified bot in your firewall or bot protection, and rate-limit or challenge requests that only claim to be it.

Frequently asked questions

What are the IP ranges of Google user-triggered fetchers?

Google user-triggered fetchers publishes 530 IPv4 and 530 IPv6 prefixes (16,960 IPv4 addresses in total) in its official list at https://developers.google.com/static/search/apis/ipranges/user-triggered-fetchers.json. This page shows the list as of Oct 1, 2026 and loads the latest copy when it opens.

How do I verify that a request really comes from Google user-triggered fetchers?

Anyone can send the user agent Google-Site-Verification, FeedFetcher-Google …. Check that the IP address of the request is in the list (use the checker on this page), or do a reverse DNS lookup followed by a forward lookup, as described in the official documentation.

How often do the Google user-triggered fetchers IP ranges change?

Providers add and remove ranges regularly, sometimes several times a week. Do not hard-code the list: load it from its source (or this page's JSON) on a schedule, for example daily.

How do I allow only Google user-triggered fetchers in nginx?

Download the nginx format on this page and include it in a location block: one 'allow' line per prefix followed by 'deny all;'. Regenerate the file regularly, because the list changes.
