What Is Google's IP Address?

Internet & Network

Updated June 08, 2017

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 like their DNS servers.

There are multiple reasons you might want to find the IP address of a website, and they apply equally to Google server IP addresses.

Why You Might Want Google's IP Address

If all is working normally, you can visit the Google search engine at google.com.

However, it's also possible to reach it by one of Google's IP addresses, even when the domain can't be reached by name.

So, if there's an issue with DNS, and Google's IP address can't be found from entering "google.com," you could instead enter the URL as a valid IP address, like http://74.125.224.72/. Other suitable addresses might work better depending on your location, but there's more on why that's the case in the next section below.

Testing connections to websites 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.

Also, website 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.

IP Addresses Used by Google

Like many popular websites, Google utilizes multiple servers to handle incoming requests to its website and services.

Google.com IP Address Ranges

The following public IP address ranges belong to Google.com:

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

Only certain addresses from Google's pool will work at any given time depending on how Google chooses to deploy its web server network, which is why a random example above may or may not work for you right now.

Google DNS IP Addresses

Google maintains the IP addresses 8.8.8.8 and 8.8.4.4 as the primary and secondary DNS addresses for Google Public DNS. A network of DNS servers strategically located around the world support queries at these addresses.

However, Google isn't the only company that offers free and public DNS servers.

Googlebot IP Addresses

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

Website administrators like to monitor when Google's crawler visits their domains. Google does not publish an official list of Googlebot IP addresses but instead recommends to follow these instructions for verifying Googlebot addresses.

Many of the active addresses can be captured from lookups:
