If I have dedicated server with lot of Ips and lot of domains and I can create seperate DNS record for each domains then how can I hide from google that I'm owner all of this ? Because when want to check it, we can always find main IP of my server which can indicate that I'm owner all of this. How to avoid this ?
Why does it matter? Contrary to claims I've heard, I've never seen a penalty for having a bunch of sites in an IP block. The game with Google is all about content and backlinks. If nothing on your sites raises red flags, Google's algorithm could care less how many domains are in your IP block.
I do not know how your business is set up but I believe in the 88 / 20 rule. Hopefully, 20 percent of your sites are the ones that are creating the revenue for you. If that is true, then you can create a couple of different hosting accounts for your most important domains.
Just search for "private whois" or "private domain registration". In GoDaddy, it cost only $10/year/domain.
