IP range JSON source renamed from googlebot.json to common-crawlers.json
Source: https://developers.google.com/search/docs/crawling-indexing/google-common-crawlers
What changed
The authoritative JSON object for common crawler IP ranges was renamed from googlebot.json to common-crawlers.json. The page’s last-updated date also advanced from 2025-04-25 to 2026-02-11.
Implication
Operators and tools that fetch or reference the googlebot.json endpoint to verify crawler IP ranges must update to common-crawlers.json. Using the old filename will likely result in missing or stale IP data, potentially breaking crawler-verification logic.
