GoogleBot
ASN OfficialAutonomous 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.
