Search crawler · user agent Googlebot

Googlebot IP addresses

Googlebot crawls the web for Google Search. Verify that a visitor claiming to be Googlebot really comes from these ranges before allowing it past bot protection.

Googlebot is the crawler for Google Search. Any client can send a Googlebot user agent, so before you exempt it from rate limits or bot rules, match the connecting IP against this list or confirm it with a reverse-then-forward DNS lookup. Google publishes its special-case crawlers and user-triggered fetchers as separate lists; include those too if you allowlist every Google fetch.

Verifying Googlebot

The user agent string Googlebot 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 Googlebot:

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 Googlebot?

Googlebot publishes 170 IPv4 and 147 IPv6 prefixes (5,088 IPv4 addresses in total) in its official list at https://developers.google.com/static/crawling/ipranges/common-crawlers.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 Googlebot?

Anyone can send the user agent Googlebot. 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 Googlebot 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 Googlebot 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.

IP geolocation API

Know who is behind any IP

Beyond published lists, the ipbase API tells you the owner, ASN and location of every IP address, and on the Medium plan and above its data-center and VPN status, so you can recognise cloud traffic and bots from any provider.
