What is the IP Address of Google?

As one of the world's largest Internet companies, Google owns a sizable amount of public IP address space. The many different Google IP addresses support their search and other Internet services including Google Public DNS.

Why Google's IP Address Matters

People can visit the Google search engine at google.com when their Internet connection is functioning normally. It is also possible to reach the site by one of its Google's IP addresses, even when the domain cannot be reached by name.

Instead of http://google.com/, for example, a person can enter

http://74.125.224.72/

(or other suitable address depending on location in the world). Testing connections to Web sites by addresses instead of names can be a helpful troubleshooting step to verify whether the connection has an issue with name resolution versus some other kind of technical glitch.

Web site administrators are often curious to know when Google Web crawlers visit their sites. Analyzing Web server logs reveals the addresses of crawlers but not their domains.

The Many IP Addresses of Google

The following IP address ranges belong to google.com:

Google IP Address Ranges
64.233.160.0 - 64.233.191.255
66.102.0.0 - 66.102.15.255
66.249.64.0 - 66.249.95.255
72.14.192.0 - 72.14.255.255
74.125.0.0 - 74.125.255.255
209.85.128.0 - 209.85.255.255
216.239.32.0 - 216.239.63.255

​Like many popular Web sites, Google utilizes multiple Internet servers to handle incoming requests to its Web site.

Instead of entering http://www.google.com/ into the browser, a person can enter http:// followed by one of the above addresses, for example:

  • http://74.125.224.72/

Only certain addresses from Google's pool will work at any given time depending on how Google chooses to deploy its Web server network.

Google DNS Public IP Addresses

Separate from google.com, Google maintains the IP addresses 8.8.8.8 and 8.8.4.4 as the primary and secondary Domain Name System (DNS) addresses (respectively) for Google Public DNS.

A network of DNS servers strategically located around the world support queries at these addresses.

Googlebot

Besides serving www.google.com, some of the Google's IP addresses above are utilized by its Googlebot Web crawlers.

Web site administrators like to monitor when Google's crawler visits their domains. Google does not publish an official list of Googlebot IP addresses but rather recommends to follow these instructions for verifying Googlebot addresses. Many of the active addresses can be captured from lookups as shown below:

Googlebot IP Address Ranges
64.68.90.1 - 64.68.90.255
64.233.173.193 - 64.233.173.255
66.249.64.1 - 66.249.79.255
216.239.33.96 - 216.239.59.128

Note this is not a complete list and the specific addresses used by Googlebot can change at any time without notice.
