Verifying Googlebot
You can verify if a web crawler accessing your server really is Googlebot (or another Google user-agent). This is useful if you're concerned that spammers or other troublemakers are accessing your site while claiming to be Googlebot. Google doesn't post a public list of IP addresses for webmasters to whitelist. This is because these IP address ranges can change, causing problems for any webmasters who have hard-coded them, so you must run a DNS lookup as described next.

To verify Googlebot as the caller:

Run a reverse DNS lookup on the accessing IP address from your logs, using the host command.
Verify that the domain name is in either or
Run a forward DNS lookup on the domain name retrieved in step 1 using the host command on the retrieved domain name. Verify that it is the same as the original accessing IP address from your logs.
Example 1:

> host domain name pointer

> host has address

Example 2:

> host domain name pointer

> host has address
