Google IP Range Checker & Bot Verifier
Comprehensive Google IP verification tool for technical SEOs. Check single IPs, bulk verify lists,
analyze server logs, and validate Googlebot with reverse DNS verification. Uses official
goog.json and cloud.json feeds with support for both IPv4 and IPv6.
API Available: Add
?api=1&ip=YOUR_IP to this URL for JSON responses.
Perfect for automation and monitoring scripts.
How to use the Google IP Range Checker
Single IP Verification
- Enter an IPv4 or IPv6 address in the IP field
- Optionally paste a User-Agent string for pattern matching
- Select verification methods (IP ranges, DNS, etc.)
- Click "Run Verification" to get a confidence score
Bulk & Log Analysis
- Switch to "Bulk Check" for multiple IPs (up to 100)
- Use "Log Analyzer" to extract and verify IPs from server logs
- Enable DNS verification for thorough Googlebot validation
- Export results as JSON or CSV for reporting
Important Notes
- IP ranges alone don't guarantee it's Googlebot - always use DNS verification for critical decisions
- Google Cloud IPs can be used by any GCP customer, not just Google services
- User-Agent strings can be spoofed - combine with IP and DNS checks
- Results are cached for 1 hour to improve performance
Understanding Confidence Scores
- 70-100% (Likely Google)
- IP is in Google ranges AND passes DNS verification or User-Agent checks
- 40-69% (Uncertain)
- Some checks pass but not all - requires further investigation
- 0-39% (Unlikely Google)
- Most verification methods fail - likely not genuine Google traffic
