What it is for

Verify that a visitor with a Googlebot user agent really is Google before you serve or block it.

$curl -s https://proxyspace.pro/ip-ranges/googlebot.txt
# Is this Googlebot? (prints it if so)
echo 66.249.66.1 | grepcidr -f <(curl -s https://proxyspace.pro/ip-ranges/googlebot.txt)

Googlebot IP ranges: questions

How many IP addresses does Googlebot use?

The official list has 170 IPv4 prefixes covering 5,088 addresses and 147 IPv6 prefixes.

How often does the Googlebot IP list change?

ProxySpace fetches it every day; the source was last updated on 2026-10-16. Rules built from it should be refreshed regularly, for example with a daily cron job that downloads the list again.

How do I check whether an IP belongs to Googlebot?

Download the list and match the address against it, or use the IP lookup tool to see the network (ASN) an address belongs to.

Where are the IP ranges of other networks?

See the IP ranges page for every cloud provider and every country, or the Tailscale page for the 100.64.0.0/10 range.
