Google Moves Crawler IP Range Files to a New General Location
Google is relocating its JSON files listing crawler IP ranges from the /search/apis/ipranges/ directory to a new, more general path at developers.google.com/crawling/ipranges/. This change reflects the fact that these IP ranges apply to a broader set of Google crawlers beyond just Search. The old path will remain accessible for up to six months before being phased out and redirected.
Key points
- Google is moving the JSON files listing its crawler IP ranges from developers.google.com/search/apis/ipranges/ to the new canonical path at developers.google.com/crawling/ipranges/.
- The reason for this migration is that the IP ranges in question apply to more than just Google Search crawlers, making the previous /search/ directory path semantically inaccurate.
- Google's official documentation has already been updated to reference the new /crawling/ipranges/ location as of March 31, 2026.
- The old /search/apis/ipranges/ path will remain functional in parallel to give teams time to update their systems and automated processes.
- Google will phase out the old location and replace it with a redirect to the new path within a window of six months from the announcement date.
- The announcement was made by Gary from the Google Search Central team, signaling an official and deliberate infrastructure decision rather than a minor undocumented change.
Analysis
The core motivation behind this change is one of organizational clarity. The IP range files have historically been housed under the /search/ path, which implied they were exclusively relevant to Google Search crawlers. In reality, multiple Google crawlers across different products and services share these IP ranges, so placing the files under a dedicated /crawling/ directory better reflects their true scope and purpose.
From a practical standpoint, this migration affects any system or workflow that programmatically fetches or references Google's IP range files. This includes server configurations, firewall rules, reverse proxy setups, log analysis pipelines, and security auditing tools that rely on these JSON files to identify and verify legitimate Google bot traffic. Teams that have hardcoded the old URL into automated scripts or monitoring dashboards will need to update those references proactively.
The six-month transition window is a considerate grace period, but it should not encourage complacency. Google has explicitly stated that the old path will eventually be phased out and replaced with a redirect. Relying on a redirect rather than a direct path introduces a marginal but unnecessary dependency, and there is no guarantee the redirect itself will be permanent. Updating sooner rather than later is the more resilient approach.
For SEO and technical teams, the indirect SEO implications are worth noting. If a server or CDN is configured to use an outdated IP list to filter traffic, it may begin blocking or rate-limiting Google bots once the old file stops being maintained and its data becomes stale. This could result in reduced crawl frequency, incomplete indexation, or delayed discovery of new or updated content, all of which can negatively affect organic visibility over time.
This update also serves as a useful reminder that infrastructure-level documentation published by Google Search Central is not static. Staying subscribed to the Google Search Central Blog and auditing technical configurations against current documentation on a regular basis is a sound practice for any organization that depends on organic search traffic.
What to do
- Update any scripts, cron jobs, or automation tools that fetch Google's IP range files to use the new URL at developers.google.com/crawling/ipranges/ as soon as possible, without waiting for the six-month deadline.
- Audit all server-side configurations, including firewall whitelists, reverse proxy rules, and CDN access policies, to ensure they will continue to correctly identify Google crawlers once the new file path becomes the sole authoritative source.
- Add the new /crawling/ipranges/ URL to internal technical documentation and onboarding materials so that future team members and contractors reference the correct location from the start.
- Set a calendar reminder or monitoring alert for within the next three months to verify that the transition has been completed across all systems, giving a buffer before the old path is decommissioned.
- If your organization uses log analysis or bot detection tools that reference Google's IP ranges, coordinate with the relevant engineering or DevOps teams to update those integrations promptly and validate that bot traffic is still being correctly classified after the change.
- Subscribe to the Google Search Central Blog or set up an RSS feed alert for it, as this announcement illustrates that technically consequential updates are sometimes published with minimal fanfare and require proactive monitoring to catch in time.
While this update does not directly affect search rankings, it is operationally important for any team that uses Google's IP range files to configure server-level access rules, firewall whitelists, or bot filtering logic. Failing to update systems in time could result in incorrectly blocking or misidentifying legitimate Google crawlers, which would indirectly harm crawl efficiency and indexation.
