What it is

GoogleOther is Google's generic crawler for product teams' one-off and R&D fetches; it is not the Search indexer (that is Googlebot) and may use separate crawl controls. Aiola classifies it as training because it performs automated collection rather than a user-triggered fetch.

In Aiola's taxonomy, Training means scraped for model training or dataset development.

User agent

Look for the match token inside the complete HTTP User-Agent header. Tokens can be spoofed, so use the network checks below for authentication.

Verify authenticity

Start with the source IP recorded by your trusted edge or server, not an untrusted forwarded header.

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"))'
Reverse- and forward-DNS double lookup
host REQUEST_IP
# Confirm the hostname ends in an official suffix
host RETURNED_HOSTNAME
# The forward lookup must return REQUEST_IP

For production checks, test against every current prefix in the vendor feed. Re-fetch feeds regularly: a July 2026 snapshot is evidence of publication, not a permanent firewall list.

FAQ

What is GoogleOther?

GoogleOther is Google's generic crawler for product teams' one-off and R&D fetches; it is not the Search indexer (that is Googlebot) and may use separate crawl controls. Aiola classifies it as training because it performs automated collection rather than a user-triggered fetch.

What user-agent token identifies GoogleOther?

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

Can I verify GoogleOther by IP address?

Google publishes a JSON feed, and this page snapshots 315 CIDR prefixes fetched on 2026-07-11. Match the source IP against the current vendor feed before trusting it.

Can robots.txt block GoogleOther?

Google documents crawler controls for this bot family. Robots.txt can direct cooperative crawling, but it cannot prove that a request is authentic. Use the specific “GoogleOther” group when you want a rule for this identity without changing rules for every crawler.
