The reason I am asking this is that I have two blocks of class c ip addresses at my colo facility. I plan on putting most of my companies sites on one block and then putting another website on the other block. The issue is that I do not have control over this other site, even though it is owned by my company and I have found that is violating Googles webmaster guidelines by serving up duplicate content. The problem is that even though it is isolated on its own class c, there will only be one firewall. So if you did a normal reverse ip or whois lookup you would see it is on its own class c. But if you did a trace route, the last jump before it gets to the domains ip would be the firewall which would have the same ip as my other class c. Hopefully, i am just very paranoid. Any thoughts on this?
IP is not the only way google can check releated sites or sites owned by same person. Many people call it a paranoia but,
With toolbars they collect data and their privacy policy says, "In addition, we use log information about aggregate Toolbar usage to improve the quality of Toolbar and other Google services." - So with a pattern they can trace two sites to be related. Am I logically correct?
Does anyone know what methods Google uses to detect a websites IP Address?
The IP address is in every packet that your site sends to every user. They don't have to do anything to "detect" it. It's a fundamental part of TCP/IP. All they have to do is examine the TCP headers of the packets your site sends. No need to do a traceroute. And anything upstream, after all, is just upstream - it's not the IP address of your website.
I think perhaps what you meant, though, is "what methods does Google use to determine website ownership." They've stated pretty clearly that they use multiple methods (at least with regard to Adwords) including manual checks. Certainly, a manual check could include a traceroute, and in the scenario you've described, the common ownership would be fairly obvious to a human observer.
Bottom line - if you think it's wrong, don't do it. A similar discussion seems to come up often regarding "private registration". There's really no such thing - it's just a matter of how motivated, capable, and legally-enabled somebody is to discover your identity.
I think you are probably overly-paranoid. However, see recent slashdot article on Google being in bed with the NSA, CIA, etc. Suggestions that they have done deals that give Google access to information (e.g. Google Earth) in exchange for technology. Now, if the NSA wants Google's technology, think you can hide from Google?
