Complete Googlebot IP Address List - Updated Daily

Complete and up-to-date list of all Google crawler IP addresses and networks (CIDR ranges). Data is fetched directly from Google Search Central’s official API and updates daily.

Why Do You Need This List?

If you manage a website, application, or server, it’s important to identify legitimate Googlebot requests:

1. Security - Block fake bots pretending to be Googlebot
2. Optimization - Prioritize legitimate Google requests
3. Monitoring - Identify Googlebot crawl patterns in logs
4. Debugging - Troubleshoot indexing issues in Search Console

Google’s 3 Types of Crawlers

Google uses 3 main types of crawlers, each with its own purpose and IP list:

1. Common Crawlers (Regular Googlebot)

Regular crawlers used for Google products like Google Search. Always respect robots.txt.

• Reverse DNS: crawl-***-***-***-***.googlebot.com or geo-crawl-***-***-***-***.geo.googlebot.com
• Quantity: 164 networks (128 IPv6 + 36 IPv4)

2. Special-Case Crawlers

Crawlers that perform specific functions (like AdsBot) where there’s an agreement between the site and the product. May ignore robots.txt.

• Reverse DNS: rate-limited-proxy-***-***-***-***.google.com
• Quantity: 280 networks (128 IPv6 + 152 IPv4)

3. User-Triggered Fetchers

Tools and functions where the end user triggers the fetch (like Google Site Verifier). Ignore robots.txt because they’re user-initiated.

• Reverse DNS:
  • ***-***-***-***.gae.googleusercontent.com
  • google-proxy-***-***-***-***.google.com
• Quantity: 1,351 networks (724 IPv6 + 627 IPv4)

How to Use This List

Check Using the On-Page Tool

Enter an IP address in the search field above and the tool will automatically check if it’s in one of the official networks.

Check Using Reverse DNS

# Linux / macOS
host 66.249.66.1

# Windows
nslookup 66.249.66.1

If it’s legitimate Googlebot, you’ll get a result like:

1.66.249.66.in-addr.arpa domain name pointer crawl-66-249-66-1.googlebot.com

Block/Allow in Firewall

If you want to block or allow only legitimate Googlebot, use the CIDR block list. Example for iptables:

# Allow Googlebot
iptables -A INPUT -s 66.249.64.0/19 -j ACCEPT

Use in Nginx

# geo block to identify Googlebot
geo $is_googlebot {
    default 0;
    66.249.64.0/19 1;
    # ... other networks
}
