<p>As one of the world&#39;s largest Internet companies, Google owns a sizable amount of <a data-inlink="Gg6t1DZqpszq92aEtL-Qng&#61;&#61;" href="https://www.lifewire.com/what-is-an-ip-address-818393" data-component="link" data-source="inlineLink" data-type="internalLink" data-ordinal="1">IP address</a> space. Many different Google IP addresses support their search engine and other services including <em>Google Public DNS</em>.</p><h3>Why Google&#39;s IP Address Matters</h3><p>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&#39;s IP addresses, even when the domain cannot be reached by name. Instead of http://google.com/, for example, a person can enter</p><blockquote><p>http://74.125.224.72/</p></blockquote><p>(or other suitable address depending on location in the world). Testing the connection by address can be a helpful troubleshooting step to verify whether the connection has an issue with name resolution versus some other kind of technical glitch.</p><p>Web site administrators are often curious to know when Google <em>crawlers</em> visit their sites. Analyzing Web server logs reveals the addresses of crawlers but not their domains.</p><h3>The Many IP Addresses of Google</h3><p>The following IP address ranges belong to google.com:</p><table border="1" cellpadding="1" cellspacing="1"><caption>Google IP Address Ranges</caption><tbody><tr><td>64.233.160.0 - 64.233.191.255</td></tr><tr><td>66.102.0.0 - 66.102.15.255</td></tr><tr><td>66.249.64.0 - 66.249.95.255</td></tr><tr><td>72.14.192.0 - 72.14.255.255</td></tr><tr><td>74.125.0.0 - 74.125.255.255</td></tr><tr><td>209.85.128.0 - 209.85.255.255</td></tr><tr><td>216.239.32.0 - 216.239.63.255</td></tr></tbody></table><p>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:</p><ul><li>http://74.125.224.72/</li></ul><p>Only certain addresses from Google&#39;s pool will work depending on the physical location of the browser.</p><h3>Google DNS Public IP Addresses</h3><p>Separate from google.com, Google maintains the IP addresses <strong>8.8.8.8 </strong>and <strong>8.8.4.4</strong> as the primary and secondary <a href="https://www.lifewire.com/definition-of-domain-name-system-816295" data-component="link" data-source="inlineLink" data-type="internalLink" data-ordinal="2">Domain Name System (DNS)</a> addresses (respectively) for Google Public DNS. A network of <a href="https://www.lifewire.com/what-is-a-dns-server-817513" data-component="link" data-source="inlineLink" data-type="internalLink" data-ordinal="3">DNS servers</a> strategically located around the world support queries at these addresses.</p><h3>Googlebot</h3><p>Besides serving www.google.com, some of the Google&#39;s IP addresses above are utilized by its <a href="https://www.lifewire.com/how-does-search-engine-work-3482032" data-component="link" data-source="inlineLink" data-type="internalLink" data-ordinal="4">Googlebot</a> Web crawlers.</p><p>Web site administrators like to monitor when Google&#39;s crawler visits their domains. Google does not publish an official list of Googlebot IP addresses but rather recommends to <a href="http://support.google.com/webmasters/answer/80553" data-component="link" data-source="inlineLink" data-type="externalLink" data-ordinal="5">follow these instructions for verifying Googlebot addresses</a>. Many of the active addresses can be captured from lookups as shown below:</p><table border="1" cellpadding="1" cellspacing="1"><caption>Googlebot IP Address Ranges</caption><tbody><tr><td>64.68.90.1 - 64.68.90.255</td></tr><tr><td>64.233.173.193 - 64.233.173.255</td></tr><tr><td>66.249.64.1 - 66.249.79.255</td></tr><tr><td>216.239.33.96 - 216.239.59.128</td></tr></tbody></table><p>Note this is not a complete list and the specific addresses used by Googlebot can change at any time without notice.</p>
