what does Google know behind a domain?

If you register a domain with a registrar. The registrar has your computer's user agent, IP address, Paypal ID, credit card number, name, address and phone number...etc.
Does the registrar pass these info to ICANN? Google will read these info from ICANN?
Will some registrar send your info to Google directly?

Once a domain is registered at a registrar. Does Google acknowledge this registration immediately? and start to recording it's DNS history?

If you use Cloudflare, will Cloudlfare automatically send your real IP to the backdoor of Google?

Google only knows what you registrar publically registers on whois registry.. You can check you domain's whois info with several online whois tools available.


And No, none of your payment info is made available to anybody..Only info which is made public is registrant's name,contact,email and abuse reporting contact,email which you provide to your registrar

Why would you wanna hide from Google? Anyway, guess what: YOU CAN'T!

1. No, I don't think the registrar shared your personal details with Google, as that would be an immense breach of their privacy policy.

2. Google itself is an ICANN accredited registrar and has access to information domains being registered newly, as well as their registration history (the latter being public info)

3. No, cloudflare does not leak your real IP. But if everything isn't configured correctly, it is simply to determine the real IP using a tool like - https://iphostinfo.com/cloudflare/

Google knows all..
