How to find out if an IP belongs to Google?

Question

Google

More than 20k requests per day from IP 213.33.200.166 with user-agent

Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)

In the terminal I do host 213.33.200.166, I get:

Host 166.200.33.213.in-addr.arpa. not found: 3(NXDOMAIN)

I understand correctly that this IP does not belong to Google and the site is stupidly parsed?

Answer 1

This IP belongs to VimpelCom, i.e. the Beeline company. It's not Google!
But why does Beeline need this? - Another question.
Although, on the other hand, perhaps this Google Global Cash.

If the host doesn't have googlebot.com or google.com it's not google
