How to find a mirror site

...that is not indexed in any search engine?

Two identical sites exist. The first one is indexed in SEs and I know everything about it.

Now, I am told an identical site also exists. I have been searching everywhere for it but to no avail. It is NOT indexed anywhere. I don't know the URL, nor the IP. I only know the content (of course). This site is rather new I would say. I have checked the IP address of the original site but there's nothing. I have also checked the IP on the advanced search in AllTheWeb as well but nothing.

How would you go about trying to find out whether a site has a mirror site somewhere if the site is not indexed? I am convinced it is impossible because logic tells me so but maybe some of you have ideas?

I do know the IP of the company that MIGHT be hosting the mirror site (not the same host as the original). But with shared hosting I could find hundreds of thousands of pages from different sites on the same IP so it would take me forever to search.

Unless it's indexed searching won't work. Someone needs to tell you.

I always search for complete text strings in google.

If you can't find the mirror, than nobody can. If nobody can find it, it won't harm you. SO why bother?

Thanks guys, I thought so.

Hugo, I wanted to find the site BEFORE any spider sniffed it up. I work in a place where web sites are incredibly messy, nobody knows who's responsible for what, people do the most insane things. Then you end up with a new client who wants SEO and you must clean up so much mess for SEO to be worth it. I just want to be able to find all the garbage myself before there's any danger to a site I'm working on.
