Block or allow it in robots.txt

Add these lines to the robots.txt file at the root of your domain. To block it everywhere:

User-agent: Google-Extended
Disallow: /

To allow it everywhere except one folder:

User-agent: Google-Extended
Disallow: /private/

Is it really this bot?

Anyone can copy a user agent, and Google does not publish IP ranges for this bot. A reverse DNS lookup of the IP address may help; check the official documentation.
