Googlebot & Bingbot IP Checker — Verify Search Engine Bots
Check whether an IP address visiting your website belongs to a legitimate search engine crawler.
Identify IPs used by Googlebot, Bingbot, Naverbot, Yahoo crawlers, and other major search engine bots.
Supports individual IPv4 and IPv6 lookups as well as CIDR IP range searches (example: 123.123.50.0/24).
You can also use Vivoldi’s IP Address Lookup Tool to check the geolocation and ISP details of a specific IP address.

Quickly check whether an IP address is used by a search engine.
Supports CIDR IP range lookups such as 123.123.50.0/24.
This IP is not used by major search engine bots.
How Are Googlebot IP Ranges Organized?
Google officially publishes the IP ranges used by its crawlers.
Googlebot operates across multiple IP blocks, including 66.249.0.0/16, with support for both IPv4 and IPv6 ranges.
Understanding these IP ranges can help diagnose crawling issues and identify unusual bot traffic in Google Search Console.
Some Google crawlers, such as Google-InspectionTool, may use separate IP ranges. For the most accurate verification, always refer to Google’s official documentation.
Why User-Agent Alone Is Not Enough to Verify Crawlers
Malicious bots often spoof their User-Agent strings to impersonate Googlebot or Bingbot.
Since User-Agent values can be freely modified in HTTP requests, relying only on the User-Agent string is not a trustworthy way to identify legitimate search engine crawlers.
To verify authenticity, you should also confirm whether the connecting IP address belongs to an official search engine IP range.
When used together with Vivoldi’s User-Agent Analyzer, you can cross-check crawler identity using both IP and User-Agent data.
How Is Search Engine Bot IP Data Updated?
Search engines such as Google, Bing, and Naver regularly update the IP ranges used by their crawlers.
Update schedules vary by provider, and some search engines may change IP ranges without prior notice.
Vivoldi automatically updates official search engine IP lists every day.
Using outdated IP ranges in firewall rules can accidentally block legitimate crawlers, so keeping IP data current is essential.
Real-World Situations Where Search Engine Bot IP Verification Is Useful
This tool is especially useful in situations like these:
- Allowing search engine crawlers through CDN or WAF security rules
- Investigating sudden increases in bot traffic within server access logs
- Checking whether a specific IP belongs to a crawler after updating robots.txt
- Separating bot traffic from real visitors in analytics and traffic reports
No installation required — use it instantly from any web browser.
Why You Should Verify Search Engine Bot IPs Before Updating Firewall Rules
When tightening server security, it’s easy to accidentally block legitimate search engine crawler IPs.
If Googlebot or Bingbot becomes blocked, search engines may fail to crawl your site correctly, causing pages to disappear from search results.
Before applying firewall or security rule changes, checking suspicious IP addresses with this tool can help prevent accidental blocking of legitimate crawlers.
Frequently Asked Questions
This tool currently supports official IP ranges for Google (Googlebot), Bing (Bingbot), Naver (Naverbot), and Yahoo.
Verification is based on IP ranges publicly published in the official documentation of each search engine. Private crawlers or internal service bots may not always be identifiable.
Support for additional search engines may be expanded in future updates.
Enter an IP address to instantly check whether it belongs to an official Googlebot IP range published by Google.
Googlebot verification is commonly performed using reverse DNS and forward DNS lookups. However, this tool directly compares IP addresses against Google’s official IP lists, allowing fast verification without additional DNS queries.
Yes, IPv6 addresses are fully supported.
Google uses IPv6 crawler ranges such as 2001:4860:4801::/48 for parts of its crawling infrastructure.
Simply enter an IPv6 address to check whether it belongs to an official crawler IP range.
This tool only verifies whether an IP address belongs to an official search engine crawler.
Generic crawlers, scrapers, and malicious bots require separate reputation or database-based detection systems, so they are not included in this tool’s verification scope.
If you want to identify the organization, ISP, or country associated with an unknown IP address, you can use Vivoldi’s IP Address Lookup Tool.
When you enter a CIDR range such as 123.123.50.0/24, the tool checks all official search engine bot IP ranges associated with that network block.
This allows you to verify an entire IP range at once instead of checking individual IP addresses repeatedly.
Each search engine operates its own data centers and network infrastructure, so crawler IP ranges are managed differently across providers.
Search engines also update crawler IP ranges on different schedules. To accurately verify whether an IP belongs to a specific crawler, it should always be checked against that search engine’s official IP lists.
