Is Google Proxy a fake crawler? For example: google-proxy-66-249-81-131.google.com

* EDIT: The solution to this question is below this question because the answer could not be posted. People decide to close the question. *

I recently discovered that some google proxy options visit my sites. I doubt that these are legitimate google crawlers because these crawlers are NOT always behind a proxy server (for example, hostname) and identify themselves as a browser. The host name is formatted in the same way as a google bot, but with the string 'proxy' added to it.

My PHP lock class blocks these crawlers, but is it right to block them? What are they and are they from Google or is it a fake?

Here you will find information about one of these scanners:
