GoogleBot
Autonomous systems and published crawler range endpoints for Google Search and Ads products. User-triggered fetches (previews, verification, agents on user request) are not Googlebot indexing; see the short guide below for the three official crawling-hub JSON feeds. For broader non-crawler Google IPs (e.g. Apps Scripts), see goog.json below; for Google Cloud egress prefixes, use the Google Cloud Platform entry (cloud.json), not these crawler feeds.

General Google IPs - goog.json Official feed
User-triggered traffic: three official JSON feeds
- user-triggered-fetchers.json / user-triggered-fetchers-google.json → IPs used when a user asks Google to fetch something from your site right now. Example: You paste your URL into Google Search Console "Test Live URL" or someone shares your link in Google Chat and Google fetches it to generate a preview.
- user-triggered-agents.json → IPs used by Google's AI/agent-like systems acting like a browser on behalf of a user. Example: A user asks Google Assistant or an AI agent to "open this page and summarize it," and Google visits your site programmatically to complete that task.
